Understanding the differences between these two materials is crucial for businesses aiming to optimize their packaging processes and meet consumer expectations.

What is Polyolefin Shrink Film?

Polyolefin (POF) shrink films are known for their clarity, flexibility, and strength. They offer excellent puncture resistance and high tensile strength, ensuring that packaged products remain secure during transportation and storage. Additionally, POF films have a high shrinkage rate, enabling them to conform tightly to the shape of the packaged item when subjected to heat.

(POF) Polyolefin Shrink Film Benefits

  • Versatility: They are suitable for packaging various items, including food products, electronics, and consumer goods.
  • Ease of use: POF films are compatible with a wide range of packaging equipment, facilitating smooth and efficient packaging operations.
  • Enhanced protection: With their excellent strength and puncture resistance, POF shrink films offer reliable protection against damage and tampering.

(POF) Polyolefin Shrink Film Applications

POF shrink films find extensive use in industries such as food and beverage, cosmetics, pharmaceuticals, and retail packaging. Common applications include wrapping individual products, bundling items together, and creating multi-packs for promotional purposes.

  • Food Packaging: Meats, cheeses, and frozen foods.
  • Beverage Multipacks: Bottled water, soft drinks, juices.
  • Cosmetics and Personal Care: Cosmetics, toiletries.

What is Polyvinyl Chloride (PVC) Shrink Films?

PVC shrink films are composed of polyvinyl chloride, a versatile thermoplastic polymer. They offer good clarity and shrinkage properties, although not as superior as POF films. PVC films are known for their high shrinkage force, which allows them to tightly conform to the shape of packaged items.

Polyvinyl Chloride (PVC) Shrink Films Benefits

  • Customizable: PVC shrink films can be customized to meet specific packaging requirements, including size, thickness, and printing options, providing flexibility for branding and labeling.
  • Shrinkage force: PVC films exhibit high shrinkage force, resulting in tightly wrapped packages with a smooth finish.

Polyvinyl Chloride (PVC) Shrink Films Applications

Despite environmental concerns, PVC shrink films are still used in various industries, including pharmaceuticals, electronics, and household products. However, their usage in food packaging has declined due to regulatory restrictions and consumer preferences for more sustainable alternatives.

Key Differences Between POF and PVC Shrink Films

The Complete Guide to Shrink Film

It's important to identify some specifics about your product to be packaged before diving into the details of the films available to you. Without question, a packaging supplier is key to selecting the appropriate film for your needs. Their industry experience and ability to understand your needs gives them the expertise to ascertain which types of films will and won&#;t work for your product.

 

Some of the packaging considerations  you&#;ll need to be aware of include:

 

  • What type of product you are packaging

  • The product&#;s weight, shape, and dimensions

  • Your objectives for color and labeling

  • Whether the film can be printed to meet your needs

  • How the product will be packaged into the flexible film (manually or via machine, and what type of machine

  • The product&#;s journey from creation to shipment to the shelf and beyond

  • Whether it will be handled often and/or subject to rough handling

  • The types of climates/environments it will experience

  • Whether it requires specific film additives to keep it fresh (e.g., oxygen or moisture barrier)

  • Requirements for anti-tampering and security of the finished good


With so many types of flexible packaging film available, you are sure to find the right packaging for your product. Whether you need an option with a high melting point, one that emphasizes durability, or one that prioritizes recyclability and sustainability, there is a shrink film product available to suit your needs. With all of the opportunities for a custom finish to any product, it&#;s always important to do your research and consider your specific needs to determine the best options.

Also, you&#;ll need to do some homework regarding equipment. If you have an automatic shrink wrapper or are planning to purchase one in the future, it&#;s important to keep an eye on your bag length and running speeds. Sometimes operators adjust the bag length from the original specs to make running the line easier. This is particularly more noticeable on older pneumatic shrink wrap equipment. Running your film at just 1" larger than necessary can equate to 2,000 extra feet of film used per day. That&#;s approximately 118 wasted rolls of film.

 

Be sure to think about how capable your internal maintenance technicians are. Adding a shrink film wrapper to your packaging line will require technical support on a regular and as-needed basis. Assess your internal maintenance team&#;s comfort level with working on the new machine(s), and make sure you have a backup technician for when service is needed and your internal team can&#;t handle the repair.  

 

Before purchasing and storing shrink film, make sure you know its storage requirements. You don&#;t want to try to work with climate-compromised packaging. Your supplier should have this information available if you&#;re unsure what your material requires. Overall, shrink packaging is best stored in temperatures between 30 and 77 degrees Fahrenheit. Naturally, summer and winter are the seasons that require you to be most attentive to your storage environment.

 

Summer:

Your facility will likely be subject to high heat in the summer, if not during springtime. If shrink sleeves are kept in temperatures exceeding 100 degrees, they may prematurely shrink and compromise their ability to protect your goods. During these hot months, keep your shrink materials stored in the coolest areas of your facility without subjecting them to refrigeration.

 

They should be kept cool, but not too cold. The coolest spots in your warehouse are typically close to the floors &#; on the lowest part of your pallet racks &#; and away from windows or places that are subject to a lot of sunlight. You&#;ll also want to keep your shrink films away from high-traffic doors because the temperatures in these areas tend to fluctuate greatly.

 

Additionally, try to schedule your shrink film deliveries early in the day. That way, the materials won&#;t sit in the back of a hot trailer when traveling from warehouse to warehouse. Not only will you avoid the harshest hours of the sun, but you&#;ll also give yourself more time to store them before the temperature reaches its peak.

 

 

Winter

:

As mentioned, packaging films tend to become especially brittle in cold temperatures, which greatly reduces their stretching and shrinking properties. While the PVC may crack, it can even shatter like glass if left in extremely cold conditions for too long.

 

As in the summer, store your rolls away from doors to avoid temperature fluctuations. You also want to ensure rain or snow won&#;t create unwanted moisture in the rolls. If you&#;ve been using PVC shrink film to package frozen foods or other products that spend time in a freezer truck or refrigerator, consider switching to a polyolefin film. This is a more durable, food-safe, and recyclable material that will keep your package intact during transit and packaging.

 

When you take shrink film out of storage, you may not know how to tell if it&#;s been compromised. One key sign is sticky rolls. If PVC rolls stick together, they were likely exposed to too much heat. Don't risk downtime on the packaging line by trying to use them anyway. Skip over the rolls that are stuck together. Bagging and sagging are also signs of overheated film. The rolls may begin to sag on the edges or show bagging within their layers. Using these rolls can interfere with the tracking on your machines, so avoid using these compromised rolls as well.



Remember, even the highest-quality shrink film and packaging materials are apt to deteriorate when subject to these environmental factors. No matter what quality film rolls you&#;re purchasing, take the time to assess how you&#;ll store them to ensure they protect and present your product exactly as you&#;ve planned.

 

Audience:

Finally, keep your target audience at the forefront of your packaging design. The type of material you choose is a part of your brand, so any disconnect between that and your brand&#;s message will confuse consumers and make them lose trust. To appeal to your customers, you have to research and understand them enough before you make these key marketing and branding decisions. Market research is a great way to learn what your target audience values and decide how to pair those details with your budget, transportation, and sustainability needs and goals. Always listen to your key demographic and cater to their needs specifically.
