POLY or PVC Shrink Wrap Uses
PVC PREFORMED WINE CAPS - Commonly used on wine and champagne bottles as a security measure.
POLYETHYLENE SHRINK BUNDLING FILM - Single wound shrink low density polyethylene generally used to shrink wrap bundles of newspaper, cases of bottled water or soda, individual boxes, etc.
POLYETHYLENE SHRINK PALLET COVERS - Clear shrink pallet covers are stock for some standard sized pallets. Custom sizes are available in a variety of sizes, gauges and prints. Shrink pallet covers are used by covering the pallet with the bag and applying heat with a hand held propane powered heat gun.
PVC SHRINK WRAP BAGS - Used for shrink wrapping a variety of small items, generally in small quantity. Bags are stocked in sizes ranging from 6"x6" up to 14"x20" . Bags with a rounded top are also stocked, commonly used for gift baskets. The bags would be sealed with a tabletop heat sealer and shrunk with a hand held 110V electric industrial heat gun.
Why Use Vapor Barriers
In
cold climates, insulation alone is not enough to keep our costly heat
from escaping. Given the slightest opportunity our precious heat will
find its way out in an alarming way.
Once we understand the
principle that warm air is attracted to cold air, and not the other way
around, it should become almost a matter of pride to keep that warm air
in! Although some heat is lost by conduction through the insulation,
most of the heat loss in a building is through air movement, or air
infiltration, through the walls.
That's where vapor barriers come in. A vapor barrier – also known as vapor retarder
– is merely a continuous sheet of impermeable material installed on the
inside, i.e. the warm side of the wall, and it's designed to keep the
warm air from escaping through or around the insulation and other
building components.
There are several reasons for wanting to keep the warm air inside the house through a vapor barrier installation; among them:
Plastic Pocket Holders
Fact Tag Holders - used by retailers to hold fact tags or signs that are attached to a specific item or along a shelf with a description of that item.
Stretch Wrap Basic FAQs
First, you need to answer whether are you applying the stretch wrap by hand or with automated equipment. If you are stretching the film by machine, you will generally use a film over 20" high and 5000 or 6000 feet long. These rolls are heavy -- about 32 lbs. Since that's a little too much to carry around a pallet, most people use 18" x .80 x 1500' rolls to stretch their pallets by hand. If your skids are not very high or if you just need to wrap the top and bottom of the loads, you could use 15" or 12".
Maybe you have seen stretch wrap used to bundle things like millwork, plastic pipe and small boxes. This is called bundling stretch wrap. It's used like tape, but it won't stick to the product or leave residue. This wrap comes in 2-6" sizes.
Can I use stretch wrap for covering my food? NO!!! Stretch wrap is not made for food contact and this industrial product should be kept away from children. Like any plastic, it can be dangerous.
Is stretch wrap recyclable? Yes, stretch wrap can be recycled through many local and state recycling centers.
Recycling Logos for Plastic Bags
20 years ago an American group came up with a numbering system to make it easy to recycle. If you mix them up recycling becomes tricky. The most useful ones for poly are:
Low density polyethylene
- used in packaging bags, grip seal, carrier bags, bin liners and heavy duty sacks.
High density polyethylene
- some carrier bags and bin liners.
Polypropylene
- used for display bags including flower bags and greetings cards.

Advantages of CAST Stretch Film
Originally, all stretch wrap was blown, a process much like blowing bubble gum. Resin is heated and passed over an opening through which air is blown. Most state-of-the-art film today is cast. It is extruded through rollers and "laid out" in sheets. This process allows the film to be made in multiple layers. The layers allow the film to be made with cling on only one side. This optional one-sided-cling film is great where you don't want one pallet to stick to the one next to it. Also, these films layers can make the film stronger by adding tough layers to the inside. Cast film is also clearer and quieter coming off the roll.
Do I need Shrink Wrap or Stretch Wrap and what is the difference
Most people who order stretch wrap from us call it shrink wrap .. but the products are very different. Shrink wrap film is made from polyolefin plastic, while stretch wrap is made from polyethylene plastic. Shrink wrap is generally used to protect a single product, such as the plastic over toys at the toy store or CD's when you first buy them. Shrink wrap gets its tight seal through a heating process. The product is wrapped and heated with a hairdryer-like tool or put through a heat tunnel. Shrink wrap can also be used for bundling products together, such as bottles of soda. We supply both stretch wrap and shrink wrap.
Stretch wrap is generally used to hold boxes on a pallet for transport. Stretch wrap is pulled around the load and stretched. The plastic has a memory and wants to return to its original size. This "elastic band effect" holds the load tight.
