4 Simple Steps to Stop and Prevent Corrosion

Corrosion, rust, oxidation, degeneration.  No matter how you say it, one thing is certain, it’s costing you money.  Quite possibly even more than you’re aware of.  The annual cost of corrosion in the production and manufacturing industry is estimated at a staggering $17.6 billion each year according to the study, “Corrosion Costs and Preventive Strategies in the United States.”  That’s just a fraction of the estimated $276 billion lost due to corrosion in the United States.  Even more alarming, the estimated indirect costs of corrosion is equal to the direct cost.  So, what steps do you need to take to ensure your products are being adequately protected from corrosion?

4 Simple Steps to Stop and Prevent Corrosion

1)  Educate Yourself  – What Exactly is VCI?

First and foremost, it’s important to understand what VCI are and how they work.  The term “VCI” stands for Volatile Corrosion Inhibitors.  Volatile Corrosion Inhibitors (VCI) are a type of corrosion inhibitors that are used to protect ferrous and nonferrous metals against corrosion, also known as rust.   Corrosion inhibitors compounds vaporize from the paper or film.  They are attracted to the charged surface of the metal due to polar orientation.

 

 

As seen in the images above, the VCI molecules align on the surface which creates a barrier that prevents oxidation.  Simply put, corrosion is stopped.  The molecules continue to build up on to the barrier surface until a continuous barrier has formed on the metal surface.

2)  So Many Choices…

It’s hard not to feel overwhelmed when you start looking at the different options available to prevent corrosion.  Paper, film, bags, and more…Oh, my!  Once you understand what choices are available to you, and what benefits each provides, the next step will be a piece of cake.  Our vendor partners at Daubert Cromwell, offer a large selection for all your VCI needs.

  • VCI Paper: Easy to use, scratch and abrasion resistant, high heat resistance and set up VCI protection quickly.   VCI Paper can also easily be converted into sheets, bags, and wraps for individual parts, to name a few.
  • VCI Films/Bags: Heat sealable, durable and stretchable, economical, high water resistance, and can be applied automatically and removed quickly.  VCI Films and Bags are easily customizable to meet all your needs.

Why Must There Be So Many Choices

  • VCI Liquids: Ideal for use to prevent rust on exposed metals and unpainted metals at all stages of their lifecycle, for lay-up and preservation of engines.
  • VCI Devices: Devices give off, or emit VCI compounds and protect recessed areas within a package.  They are ideal for hard to reach areas and enhance protection by giving a ‘boost’ of available VCI.
  • Rust Remover: Used when it’s necessary to remove rust from metal before packing, storing or shipment.  Daubert Cromwell offers a liquid and gel form of rust removers.

3)  Selecting the Right VCI

When selecting the right VCI for your application, it’s crucial to know that the VCI protection is a function of what metals are in need of protection, corrosion inhibiting chemicals used, and the ratio of chemicals in the formulation just to name a few.  It’s important to note that VCI formulations that work under one set of conditions may not work under another.   All aspects of the process, metals composition, packaging, storage and shipping conditions should be considered in order to select the right packaging media and VCI formulation.

 

With the help of your R.V. Evans Packaging Solutions Specialists, and a Site Needs Analysis, we can assist you with selecting the appropriate VCI product by taking the following into consideration:

  • Type of metals in need of protection
  • Duration of protection required
  • Domestic or export shipping
  • Climate conditions
  • Size and weight of product
  • Value of product
  • Current packaging requirements
    • Handling
    • Automatic or manual
  • Chemical or oil residue on the metal
  • Processing and cleaning methods
  • Packing station location relative to other processes

4) A Few Final Thoughts

You’ve gone through the motions of learning what VCI are, the types of VCI and how to select it.  So, it only seems fitting you know how to properly use it.  First and most important:  Employees that are packaging your products should ALWAYS wear gloves while handling metal parts.  

safety

  • Parts should be clean and free of fingerprints before wrapping.
  • Package your clean products as quickly as possible.
  • The metal part should be no more than 12″ from the VCI product.  The closer to the metal, the better the corrosion protection.
  • As a general rule, use 1 sq. ft. of VCI for every 1-3 sq. ft. of the metal surface.  Use at least 1 sq. ft. of VCI for every cubic foot of void space.
  • The duration of protection depends on the VCI paper and packing method used.
  • Packages may be opened and resealed without affecting the corrosion protection. (Avoid touching metals during an inspection.)
  • Do not inventory more than a six month supply of VCI paper or film.

Feeling Prepared?

Whether you’re new to the world of corrosion prevention or looking to add to your current corrosion prevention application, you’re now one step closer to stopping and preventing corrosion.  Are you still uncertain about what VCI application best suits your needs?  R.V. Evans company can assist you in determining and implementing the best solution for your requirements.

Rising Turnover Costs in Manufacturing: Mitigation Through Automation

Employee turnover can be expensive. In fact, Josh Bersin of Deloitte believes the cost of losing an employee can range from tens of thousands of dollars to 1.5–2.0x the employee’s annual salary. These costs include hiring, onboarding, training, ramp time to peak productivity, the loss of engagement from others due to high turnover, and higher business error rates. (Altman, 2017).

In a time when speed-to-market, low defect rates, and low cost-per-unit levels drive profitability more than ever, manufacturers are particularly affected by employee turnover. In 2016, manufacturers experienced turnover rates of 16%. (Bares, 2017). Doing the math, one can see that if their company turns over 16% of their operating workforce, and turnover costs are 2x the lost workers’ salaries, then annual turnover costs can equal up to 32% of your total operating payroll per year (assuming equal wages for simplicity’s sake). The “learning curve” effect also plays its part in higher defect rates and lower productivity, decreasing product quality and speed-to-market (Argote and Epple, 1990). In other words, turnover can severely affect profitability, especially in manufacturing.

So, what can manufacturers do about it? The psychology and social science on this subject has been published for many years, yet turnover rates are still high and have risen consistently over the past five years. Let R.V. Evans Company take a different approach. If you’re a manufacturer, do any of these activities fall under any of your workers’ job descriptions?

  • Forming cases and boxes
  • Closing and stapling boxes/cases
  • Sealing/taping cases
  • Bagging parts
  • Stretch-wrapping pallets
  • Printing images, date and batch codes, or barcodes on products or cases
  • Applying labels
  • Manually creating void-fill protective packaging for cases
  • Manually shrink-wrapping products
  • Applying strap to bundles, boxes, pallets, etc.

If you answered yes to any of those, there is room for automation.

Automation doesn’t always come in the form of complete robotics; there are ways to semi-automate as well. Semi-automation reduces the amount of laborers required to perform certain tasks in the manufacturing process, particularly in packaging processes. Examples of automation and semi-automation include:

  • Incorporating a WFPS 3290 Combo to allow a single operator to form, pack, and seal up to 30 cases per minute
  • Using an AutoBag 550 to allow a single operator to bag up to 45 parts per minute
  • Install an Orion Flex Series stretch wrapper to wrap pallets much faster than by hand
    • with a 260% pre-stretch that can save up to several thousand dollars in stretch wrap per year
  • Implementing a Samuel Model P715 automatic plastic strapping machine to apply plastic strap to your packages at speeds of up to 60 straps per minute- without an operator
  • Connecting many of these systems and others via conveyor equipment
  • Much, much more

There are numerous ways R.V. Evans and its team of packaging solutions representatives can help you reduce turnover by eliminating some of those high-turnover positions entirely. This is not a recommendation to replace your good, high-quality people that make your operation great. This is a recommendation to allow R.V. Evans to help you find ways to eliminate positions that are difficult to keep occupied due to high turnover. Equip your good workers with the means to produce more and add more value- at a lower total cost. Automating, semi-automating, and/or streamlining your processes can increase your speed to market, decrease your cost-per-unit, lean out your labor force, and make you more money.

Automated Packaging Systems – Poly Bagging Solutions Part 4 of 4 – Selecting the Right Poly Bag

In part one, we discussed if an automated packaging system is right for your company, along with an overview of various poly bagging systems in part two, and the different infeeds and printers for bagging systems in part three. Now, it’s time to figure out the “right” bag for your poly bagging application! What are the different materials available? Which bag dimension and thickness is best? What are your options? Let’s find out.

Food-Industrial-Bag-CollageWhat are the different materials available?
Autobag has many different options when it comes to poly bags that are specifically designed to work with their different poly bagging systems. These bags are storefront ready and can be printed in full color. Just a few of the options are Linear Low Density Polyethylene, Low Density Polyethylene Films, High Density Polyethylene Film, Polypropylene Film, and Anti-Fog. There are many more materials to choose from, and highly likely there will be bagging materials that fit your company’s needs.

  • Linear Low Density Polyethylene is strong material, durable, and has clear through opaque combinations ranging from blank to custom printed. It is ideal for packaging hardware, automotive parts, food, craft items, medical devices, electronic components, and many more.
  • Low Density Polyethylene Films are durable, versatile, and have different printing characteristics. They are ideal for retail packaging, hardware, fasteners, automotive parts, medical, frozen foods, mail order fulfillment, and others.
  • High Density Polyethylene Film has reduced chemical additives and good permeability. It is also scratch-resistant. This material is used for packaging medical, food, sporting goods and other applications where chemical additives may react with the product inside.
  • Polypropylene Film has the best bag clarity, good seal strength, and resists odor transfer. It is used for foods, pet supplies, and other retail packaging.
  • Anti-Fog materials are best for fresh produce applications. When condensation forms within the bag caused by product respiration, the material does not allow the moisture to form water droplets. This provides great clarity and strength.

Which bag dimension and thickness is best?
Choosing the right poly bag for your product can be difficult. It depends on the weight, size, shape, pieces going in a bag, and other factors. Autobag’s poly bags range in size and mil thickness. To identify the ideal poly bag for your packaging application, R. V. Evans Company would obtain a sample of the product you would be bagging to perform an application analysis. From there, R.V. Evans Company would provide you with a complete poly bagging system recommendation to include bagging equipment, accessories & printers, and the right poly bag for your particular bagging application.

What are the additional options?
Autobag’s poly bags come with many different features to make your product more appealing, provide added security, or reduce your packaging requirements. Just a few are:

Custom printing

Blown Film vs. Cast Film

When it comes to making a decision on which film to use for industrial films, bags, and sheeting the best starting point is to determine whether or not the application would be best served with blown film or cast film. There are major differences in the manufacturing process for each, as well as the benefits and drawbacks to each type of film. Additionally, most manufacturers specialize in either blown film or cast film.

blown film illustration

Blown Film Process Illustration

Blown Film is manufactured through a process in which plastic resin is heated and stretched to the desired thickness by an air inflation system, resulting in a very large bubble of film that is allowed more time to cool by the surrounding air. 

 

 

Cast Film Diagram

Cast Film Process Illustration

Cast Film is manufactured through a process where plastic resin is heated and stretched to the desired gauge and then as soon as it completes the heating process, the film is rolled over chilled rollers to cool the film. 

There are advantages and disadvantages to blown film and cast film that will determine which type is preferred for each application. These characteristics and properties are a result of the manufacturing process of each.

Blown Film Properties

ADVANTAGES DISADVANTAGES
Maximum Toughness Noisy Unwind
Puncture Resistance Less Control over Thickness
Less Scrap when Manufactured Longer Cooling Times
High cling
Short Production Runs Available

Cast Film Properties

ADVANTAGES DISADVANTAGES
High Transparency, Haze, Gloss Double-Sided Cling (Naturally)
Uniform Thickness/Gauge High Gloss = Glares, Reflections
No Limits on Thickness Longer Production Runs
High Barrier for Gases, Moisture, Aromas More Scrap
Quieter Unwind

 

Relevant Applications

Blown film is most commonly used in tube form (bags and sacks) or sheets, shrink film, stretch film, bags, liners, laminated film, barrier film, medical grade film, and agricultural film. Thickness typically ranges from 0.5 mil to 10 mil. Mostly in applications where clarity is not critical, but strength is. Blown film can be used in simple processes: mono-layer (bags), and complex processes: multi-layer structures (food and medical packaging).

Cast film is commonly used in thermoforming applications. Additionally, you will use cast film in most retail applications where clarity and uniform thickness are important (bakery items, flower wrapping, photo album covers, etc.).

The applications for blown film and cast film are diverse and unique. There may be a better solution for your current application.

Industrial Packaging: Functions and Materials

Industrial packaging includes a variety of materials, forms, applications, and equipment. There are multiple facets of industrial packaging, including Primary Packaging, Secondary Packaging, the function of each type of material, and the variety of applications in which you can utilize plastic industrial packaging. 

Industrial-Shrink-Film-on-a-Roll-Photo

Primary Packaging

Industrial packaging can refer to primary packaging – the packaging in which products are brought to market – (a good way to think of this is it’s often the last thing that you toss when the product is consumed, or it’s the packaging that comes directly in contact with the product)

Packaging Product
Bottles Soda, water, juice
Tubing Toothpaste, cosmetics,
Boxes Crackers, household goods, electronics
Jars Candles, Salad Dressing
Clamshells (plastic cases) Hardware (nuts, bolts, etc.), Toys
Shrink film Frozen Pizzas, Apparel

Secondary Packaging

Secondary packaging refers to protective packaging, including strapping, edge protection, stretch film (palletizing), envelopes, etc. This is the packaging that is used to protect the product in transit, storage, and on the shelf. Secondary packaging also includes –

   Air pillows         Air cushions
   AirPouches         Void fill
  Paper void fill         In-the-box-paper packaging
  Foam-in-place         Rolled bubble and foam products
  Corrosion prevention         Bubble wrap
  Paper liners         Air pouches
  Packing peanuts         Corrugated boxes
  Protective sheeting

What it’s made of: Polyethylene Film

One of the most prevalent materials in the flexible packaging industry is polyethylene (PE) film. Polyethylene is made from ethylene gas and is versatile, tough, has good clarity, and there are several variations with distinct and specific characteristics that make it a preferred material for industrial packaging applications.

There are several variations of PE film that are regularly used; three of the more popular types are LDPE, LLDPE, and HDPE. PE film is a popular flexible packaging material because of its relatively low cost, sealability, moisture barrier, and tear resistance. Its applications are versatile, ranging from uses within the agriculture, construction, and manufacturing industries. There are several different types of PE, three of the most common are:

  • LDPE – Low Density Polyethylene film
    • LDPE film is known for its toughness, flexibility, and fair transparency.
  • LLDPE – Linear-Low Density Polyethylene Film
    • Characteristics of LLDPE film include its high tensile strength, high impact and puncture resistance, flexibility, and resistance to chemicals and UV radiation.
  • HDPE – High Density Polyethylene Film
    • HDPE film is known for its high clarity and scratch resistance. HDPE film is harder, stiffer, and stronger when compared to LDPE film.

Applications for LDPE, LLDPE, HDPE films

LDPE film is often used to produce

  • Bags:
    • dry cleaning bags
    • newspaper bags
    • bread bags
    • frozen food bags
    • household garbage bags
  • Other uses include:
    • shrink wrapping
    • stretch wrapping
      • Stretch wrap is available in “hand wrap” or for “machine use”
    • bags on a roll
    • bubble packaging
    • industrial liners
    • container lids
    • toys
    • squeezable bottles

LLDPE film is used in the same applications as LDPE along with applications that require more toughness and sealability.

  • Hardware
  • Automotive parts
  • Food
  • Craft items
  • Medical devices
  • Electronic components
  • Retail applications

HDPE film is used in similar applications as LDPE and LLDPE films. HDPE is stiffer than other PE films, which is beneficial when packaging needs to retain its shape

  • medical
  • food
  • sporting goods
  • any application that might result in chemical contact with the film

These types of films are used for protective packaging, satisfying the needs of small operations (with 5 to 10 packages per day) and large operations packaging product around the clock. Different forms everyone is familiar with are bags, sheeting, tubing, casing, and liners. When you purchase anything that needs to be assembled at home, the hardware is in a PE film bag. When you see a home renovation or remodel, the plastic sheeting that is often protecting the floor or furniture is PE film. Trucks hauling equipment or pallets that are covered by plastic sheeting – polyethylene film! Garbage liners and mattress bags are also made from polyethylene films.

When it comes to industrial packaging and uses, PE film is one of the most common. You’ll find it in primary packaging, secondary and protective packaging. You’ll also find PE film in several different variations, serving multiple purposes because of its versatility and affordability.
