CALPACKTM POF Shrink Film 

Q & A

A type of POF shrink wrap that has become the preferred choice for packaging products both edible and non-edible. POF Shrink wrap is preferred for a variety of reasons including: fewer odors when sealed, stronger seal, and more flexible storage. POF shrink films do not have any chlorine; therefore they do not produce hydrogen chloride gas. POF shrink wrap does not have any plasticizers, so temperature is not an issue. POF can be stored in a wide range of temperatures and does not harden and soften in different environments like PVC shrink film does in the same condition. 

Common Uses of POF Shrink Film- POF shrink film is used for almost every kind of application. Applications include: cosmetic, pharmercy, electronic, toys, sporting goods, printed wrap, foods, stationary and cards just to name a few.

Drawbacks of POF Shrink Film- Cost and machine compatibility are the two major drawbacks of POF shrink film. POF is commonly more expensive than PVC shrink wrap. Many packagers prefer PVC because of this reason. There are types of POF shrink wraps that are more compatible with machines.

Frequently Ask Shrink Wrap Questions 

How Do I Measure For Shrink Film?

Measuring for POF shrink film is fairly simple, but is determined by the type of POF shrink product you intend on using. See below for measurement formulas for each type of film. Remember if the exact size needed is not available go to the next size up. All of our shrink film has a shrink rate of at least 30%.

Centerfold Shrink Film Measurement Formula

Width + Depth x 2 x 1.1÷2 = Centerfold Film Width Needed

Shrink Bag Measurement formula

The same formula as above to determine the bag width, for length add an additional 1-2 inches to allow space for making a seal.

Shrink Tubing Measurement formula

For squared objects use the same formula as above, but most people use tubing for cylindrical objects. If measuring for a cylindrical object use the formula below.

Circumference x 2 x 1.1÷2 = Tubing Width Needed

When Do I use Shrink Film and when do I use Stretch wrap?

Shrink wrap is commonly used to protect and package a single product, like toys or a lipstick. It also is used to help bundle multiple products together. It is often used to bundle soda, water bottles, and various other packaged products together.

Usually stretch wrap is used to hold boxes and products together on a pallet for transportation. It can also be used to hold other objects together for transportation or storage. Stretch wrap can come in a variety of specialty films. Some examples are: UV stretch wrap, vented pallet wrap, anti-static stretch film, colored stretch film, pre-stretched stretch film, etc.

Is shrink wrap and stretch film recyclable? 

Both shrink wrap and stretch film are recyclable. Check with your local recycling center and be sure they accept soft plastics.

Do I need a special shrink wrap machine? 

Different applications require machinery. When using POF shrink wrap, a heating instrument will be needed to shrink the film. There are a variety of instruments to use depending on what you are trying to accomplish. Common instruments are L-Bar sealers, I-Bar Sealers, and shrink tunnels.

Will a shrink wrap machine cut & seal the POF shrink wrap all at once?

Yes, most shrink wrap sealers cut and seal the shrink wrap film in one motion. Once sealed and cut, the scraps can be easily peeled away and heat can be applied to the shrink wrap. The heat will reduce the size of the shrink wrap film and help to conform it to the product. And also you can adjust the process to cut first then seal depends on what you will need. Please see our website as well.

What gauge of POF shrink wrap do I need?

We recommend a 75 gauge shrink wrap for products less than 12 pounds. A 100 gauge shrink wrap is recommended for products up to 30 pounds in weight. To view our gauge conversion chart, click here.

Common Shrink Wrap Terms

Centerfold Shrink Film- Film that has been folded in half lengthways to make wrapping easier and quicker.

Crow's Feet- Wrinkles diverging out from a finished package's corners

Dog Ears- Triangular projections of unshrunk film at the corners of finished packages. Common in packages wrapped with PVC shrink wrap.

Gauge- A measurement used to describe film thickness. One gauge is equal to .254 Microns. View our gauge conversion chart for further clarification.

Impulse Sealer- A sealer that uses a heating element that is pulsed with voltage during sealing.

L-Bar Sealer- A sealer where the sealing surface is in the shape of an backwards "L". A common sealer for people wanting to seal faster than using an impulse sealer. 

Lap Seal- Making a seal using two layers of shrink film lapped over each other.

Machine Direction- The direction the film is manufactured and moves through the sealing equipment.

Memory- The ability of a shrink film to maintain characteristics after sealing

Optics- The visual properties of a shrink or stretch film.

Polyolefin- A polymer produced from a simple olefin (also called an alkene with the general formula CnH2n) as a monomer. Shrink film made from this and is commonly referred to as POF shrink film.

PVC- Polyvinyl Chloride, a thermoplastic polymer that is the third most produced plastic in the world. PVC shrink film is a common shrink wrap used for various applications.  

Shrink Tunnel- Equipment that uses a chamber to produce heat with a continuous conveyor running through the chamber.

Tear Resistance- The ability of a film to resist tear. Using a shrink film with a higher tear resistance is important when wrapping heavy products or products with sharp edges.

Industries That Commonly Use POF Shrink Wrap

Games & Sporting Goods- Manufacturers, resellers, wholesalers, and retailers commonly use POF shrink wrap for wrapping a variety of goods and products. PVC shrink wrap is commonly used for these items too. It helps to detour and detect tampering and is an affordable form of packaging.

Printing & Paper Products- Many companies in this industry use POF shrink wrap to protect their products and goods as well as detouring and detecting tampering.

Food- One of the largest industries that commonly use POF shrink wrap. Wrapping in shrink film helps to remove oxygen contact from the food and can reduce waste. POF (Polyolefin) shrink wrap is the common shrink film used for food packaging. Be sure the POF shrink wrap you choose is FDA approved for food contact.

Hardware & Housewares- Many manufactures and retailers in these industries commonly use POF shrink wrap to detour and detect tampering. They also commonly use POF shrink wrap to bundle multiple products together.

Electronics- The electronics industry commonly uses POF shrink tubing and shrink wrap. Shrink tubing is commonly used in electronics for abrasion resistance and environmental protection for exposed electrical wires in various components. They also commonly use PVC shrink bags, and centerfold PVC shrink wrap to package a variety of products in.

Pharmaceuticals- This industry makes use of POF shrink wrap to help seal caps and offer the ability to detect tampering.

Cosmetics- This industries is our major customers of POF film and machine. It can provide a good looking products display and good protection.

Miscellaneous- There are a variety of other industries and uses for POF shrink wrap. The marine industry commonly uses POF shrink wrap to winterize boats and protect them from environmental elements, there are multiple uses for POF shrink wrap across many industries and we Full-More ( Shanghai) Equipment & Materials Co. Ltd would love to assist you with your POF shrink wrap needs.

Common Shrink Wrapping Problems

Wrinkles- One of the most common problems found with companies new to POF shrink wrapping. Wrinkles in the shrink film after heat is applied means more heat should be applied to the film. If the tunnel is too high temperature will apply more heat to wrinkled areas. If using a heat tunnel either slow down the belt speed or increase the heat.

Dog Ears- POF Shrink film bunched up in the corners of the package. Another very common problem when shrink wrapping. Dog ears will happen in almost any shrink wrapped package, but excessive dog ears can be prevented by applying more heat to the shrink film.

Ballooning- Excess air trapped inside the sealed POF shrink film. Ballooning happens after the seals have been made and heat is applied. It is hard to determine which products will balloon. If ballooning is experienced, small needle sized vent holes can be used to prevent future ballooning. We sell perforated shrink film rolls and bags to prevent ballooning.

Burn Holes-  Burn holes are when to much heat is applied to the POF shrink film being used. If using a shrink tunnel, speed up conveyor or decrease heat.

Shrink Film Tears- Tears in POF shrink film are often caused from the type of POF shrink film being used or the thickness of film being used. If experiencing tears, a thicker film should be considered or a different kind of film should be used. If using PVC please switch to a POF film
