Shrink Wrap 101

The term “Shrink wrap” is used to describe a myriad of shrink wrap applications and can involve the use of many different types of shrink wrap products. Some of the most common shrink wrap applications are described as “polyolefin center-folded” and “single-wound shrink wrap”. Other types of shrink wrap commonly used is “PVC center-folded shrink wrap” and “boat shrink wrap”.

In addition, you may find a need to utilize “PVC shrink wrap collars”, or “PVC preformed shrink wine caps”, or “polyethylene bundling shrink wrap”, “polyethylene shrink pallet covers”, “PVC shrink wrap bags”, or “polyolefin shrink wrap bags.”

Depending upon the type of products you have and the manner in which you offer your products will determine the specific type of shrink wrap product you need to order. Allstar Supply offers expertise in all aspects of shrink wrap products so any questions you have can be answered fully along with the appropriate guidance from one of Allstar Supply’s expert sales representatives today.

Shrink Wrap: Polyolefin Center-Folded

This particular type of shrink wrap is commonly used for shrink wrapping reams of paper, books, journals, magazines, and other types of small parts or groups of small parts. This type of shrink wrap will generally work well on most commercially-available L-Bar Sealers, including semi-automatic and automatic machines.

Your product will be wrapped in the shrink wrap film with an air vent installed and then that shrink wrap is shrunk using a heat gun or shrink tunnel. Some types of shrink wrap can also be used in food applications which require FDA approval if you intend to achieve direct food contact. Polyolefin offers high clarity with up to 15% to 20% shrink reductions in all directions.

Allstar Supply carries a variety of this type shrink wrap in stock, including a range of thicknesses (45, 50, 60, 75, and 100 gauge).

Shrink Wrap: Polyolefin Single-Wound

This particular type of shrink wrap has the same applications and properties as the center-folded shrink wrap. However, this type of shrink wrap is “only” used on high production, high speed, automatic shrink wrap applicators.

Allstar Supply carries a variety of this type shrink wrap in stock, including a range of thicknesses (45, 50, 60, 75, and 100 gauge).

Shrink Wrap: Center-Folded Machine Wrapping

This particular type of PVC shrink wrap is commonly used for many types of shrink wrap applications. For example, PVC shrink wrap would be a good choice if the product has sharp edges, points, or any type of uneven shape.

PVC has greater puncture and tear resistance than polyolefin. PVC shrink wrap also offers variations, a percentage of shrink and also you get to choose the direction of shrink. If a PVC shrink wrap was 20/40 as an example, that means the shrink wrap would shrink 20% in the machine direction (in the direction it is wound on the roll) and 40% in the transverse direction (across the width of the roll).

The most common PVC Shrink wrap is 40/40 which allows it to shrink to half the size of polyolefin. PVC is not FDA approved for use in food product wrapping applications. Another adverse consequence of utilizing PVC shrink wrap is that smoke can occur during the sealing process and would require you to offer your employees substantial ventilation in the product-seal work area.

This PVC shrink wrap will generally work well on most brands and most models of semi-automatic or automatic “L” Bar Sealers. The product you are intending to seal must be fully sealed in the film with some type of air vent installed and then your wrapping is shrunk with a heat gun or shrink tunnel.

Allstar Supply carries a variety of this type shrink wrap in stock, including a range of thicknesses (60, 75, 100, and 125 gauge).

Shrink Wrap: Boat & Marine

This particular type of boat shrink wrap is a heavy duty shrink wrap made from polyethylene. This boat shrink wrap is available in stock in several colors (Blue, White, and Clear). You can order boat shrink wrap in 6 mil and 7 mil thick ranging from 12 feet up to 36 feet wide.

This boat shrink wrap is commonly used to shrink wrap boats, water-craft, and other marine vessels during inclement weather and during harsh winter months. Another popular use of boat shrink wrap is for use on any other type of large item you seek to preserve from exposure to inclement weather regardless of the time of year, regardless of whether or not it is warm or cold.

An example of a popular use for heavy-duty marine-grade shrink wrap is utilized to protect exterior furnishings, playground equipment, and other types of heavy-duty applications such as building supplies, and above-ground pools during low-activity periods. This type of protect-travel use is prevalent for “snow-birds” who travel south to vacation during winter months up north.

Boat Shrink Wrap: More Advantages

All variations of marine-grade shrink wrap offers UVI protection (ultraviolet inhibitor) to prevent the polyethylene from breaking down while exposed to ultraviolet rays. Marine-grade shrink wrap also offers EVA (Ethyl Vinyl Acetate) to keep the polyethylene soft and flexible in sub-freezing temperatures.

Boat Shrink wrap tape is available for seaming boat shrink wrap ends together. Boat Shrink Wrap can be applied by draping the boat shrink wrap over your boat and by applying heat with a hand-held propane heat gun. This type of boat shrink wrap is a one-time use application.
