Selecting a Stretch Wrapper: What to Consider

Selecting a new stretch wrapper can be a daunting task. Here are a few tips to help simplify this task and help you select the wrapper that most positively affects your bottom line for years to come.

First, let’s reiterate why we stretch wrap. We stretch wrap loads with two primary objectives:

  1. Get your load from Point A to Point B without damaging the contents
  2. Perform objective #1 as cost-effectively as possible

When it’s time for a new stretch wrapper- whether it’s your first machine, you’re considering an additional machine, or you’re upgrading into a more advanced machine- there are some important things to consider.

Consider the load.

  • What exactly are you wrapping and what’s the current process like?
  • What are the physical attributes of the load (height, width, length, weight, etc)?
  • Is it an A, B, or C type load? Don’t know? We can help. Click here.
  • How many of these loads per day do you need to wrap?
  • How are the pallets handled (pallet jacks, fork lifts, etc)?
  • What are your needs for pallet-per-hour capacity? Think both short- and long-term.

How exactly should you wrap each individual load?

  • What types of film should you use?
  • How tightly do these loads need wrapped?
  • What wrap pattern(s) should you use?
  • How many different “recipes” do you need (wrap pattern, tightness, etc)?

What is best for you in terms of field maintenance?

  • How much maintenance will be involved with your new machine?
  • How easily modified is this new machine? Your needs will very likely change over time.
  • Are the parts proprietary?

Productivity enhancements and value-added features

  • How much film pre-stretch is best for you? Need help understanding pre-stretch? Click here.
  • Will you benefit from an automatic film attach/cut/wipe-down? See an example here.
  • Do you need an integrated scale?
  • How much will pallet conveyors help you?
  • What features can help you reduce labor and non-value-added activities? I.e, getting on and off the forklift for each load, etc.
  • What features would help your operators work more safely?

Training and support

  • How will your operators be taught how to properly and effectively use this machine?
  • If you run into the unexpected, will your vendor be there to help you?

Good and confused? That’s okay! R.V. Evans is here for you. There is no need for you to be an expert on all of this. We’ve got those experts for you! This is simply a breakdown of important things to consider as you engage in a conversation with the R.V. Evans team about your next stretch wrapper!

Why Thickness and Price are not Indicators of Tape Quality

When many manufacturers go to market in search of tape to use for case sealing applications, the primary concern often seems to be the tape’s thickness (in mils) and the price. Purchasers often think to themselves, “Okay, which tape has the best mil rating/price ratio?”. However, this can cause many problems.

Let us take a look at a comparison between Shurtape’s AP 180 emulsion acrylic carton sealing tape vs. a competitor’s version.

Shurtape Competitor
Mil 1.9 1.9
Tensile (lbs./in. width) 27 30
Adhesion to Steel (oz/in. width) 44 4
Elongation % at breaking point 150 130
Holding Time (in hours) 15,000 6,000
Figure 1

Figure 1 indicates that the Shurtape brand shares the same mil rating as the competitive tape, and even has a lower tensile strength. However, 27 lbs./inch width is still relatively strong! Additionally, Shurtape’s version maintains 11x the adhesion to steel than the competition, a longer elongation-to-break, and a much longer holding time! This longer holding time and better elongation rate both translate to more economical tape usage and a much longer-lasting seal on your packages. If you are in need of a strong seal that will last long enough for your needs, Shurtape is the way to go.

Of course, it always comes down to the application and its needs. No tape is the single best tape. However, in search of your next tape source, it is very important not to default to the very common, yet flawed analysis of mil thickness/price.

Unitizing and Stabilizing Your Products: Strapping

Strapping, also known as banding or bundling, is a common way to unitize, stabilize, and secure products. The strapping process involves applying straps (or bands) to a unit or collection of units in order to hold those units in place, or to further secure boxes or crates in which products are packaged or stored. An example of a strapped pallet of products is shown in Figure 1.

Many applications involve strapping individual boxes for further package integrity. An example of such is shown in Figure 2.

The straps help hold the boxes in place, providing stability and therefore protection for the products inside the boxes. Combining strapping with stretch wrapping and corner board provides for a well-protected pallet of product. An example of such is shown in Figure 3.

Types of Strap

There are many different types of strap. However, these many types fall under two primary categories: steel and plastic.

Steel Strap

Steel strap is used for medium- and heavy-duty applications. Steel strap is manufactured with many different widths, thicknesses, tensile strengths, etc.- all designed for a certain set of applications. Determining an appropriate type of steel strap is best performed by an R.V. Evans solutions representative. 

Plastic Strap

Plastic strap is used for light- and medium-duty applications. There are three primary types of plastic strap: nylon, polyester, and polypropylene. Additionally, each of these three material categories have been included in many different products designed for different applications. Determining the appropriate plastic strap for your application is best determined by an R.V. Evans solutions representative.

Strapping Equipment

Strap can be applied with manual hand tools, battery-operated hand tools, pneumatic tools, or semiautomatic and automatic strapping machines. Each type, size, and model of strapping tools provide a unique set of benefits. Finding the best one for you is, of course, best performed by an R.V. Evans solutions representative.

According to Merriam-Webster, ergonomics is a science that deals with designing and arranging things so that people can use them easily and safely.  Although the R&D departments of manufacturers are sure to design all of their products to fit into this mold, they unfortunately don’t have the time or the resources to make sure that the correct product is being used to its greatest capacity to ensure an ergonomically sound process.  That is where distributors like R.V.
