What is Shrink Film and Why is it Important?
Imagine a superhero for your products during shipping and storage! That&#;s shrink film in a nutshell. It&#;s a thin, stretchy plastic wrap that keeps your products safe and looking good when they reach your customers.
Here&#;s why shrink film matters:
It acts as a barrier against dust, moisture, and accidental bumps and scrapes.
The tight seal makes it hard for anyone to mess with your products.
Shrink film is lightweight, which can lower your shipping fees.
Neat and protected products project a professional image and make customers happy.
: This is your everyday hero, the most popular choice because it&#;s clear, affordable, and easy to work with. Think of it like a stretchy plastic bag that shrinks tight with heat.is perfect for lighter items like books, clothes, or bundled products.
: Need something a bit tougher? MDPE is your friend. It&#;s stronger than LDPE and can handle heavier products without tearing. Think of it like a thicker, more heavy-duty version of shrink wrap. Ideal for irregularly shaped items like toys or boxes with sharp edges, or even heavier things like books in bulk.
This type is the ultimate shrinker, like a super-powered wrap that hugs your products tightly. It&#;s also great for situations where the temperature might change during shipping, keeping everything secure. Plus, it&#;s tamper-proof, so no one can mess with your products. However, some people prefer not to use PVC because of environmental concerns.
: Looking for crystal clear and super safe? POF takes the crown. It&#;s so clear you can see everything through it, making it perfect for medical supplies or products you want customers to see clearly. Bonus: It&#;s also approved for food contact, so you can use it for things like wrapped snacks.
Remember: When choosing your shrink wrap, consider the weight and shape of your products, if they need extra protection, and if clarity is important.
Finding the Perfect Fit: Shrink Film Thickness Explained
Shrink film comes in different thicknesses, just like your favorite sweater comes in light and heavy versions. We call this thickness the &#;gauge.&#; A higher gauge means a thicker film, while a lower gauge is thinner but still strong.
Why Thickness Matters:
Choosing the right gauge is important because it affects how well the film protects your products. Here&#;s the key:
: A film that&#;s too thin might not be strong enough to protect your products during shipping or storage.
: A film that&#;s too thick can be wasteful and cost more.
Finding the Goldilocks Gauge:
The best gauge depends on the size and weight of your products. Think of it like wrapping a gift: a small box doesn&#;t need a ton of wrapping paper, but a bigger box might need something more substantial.
Quick Gauge Guide:
Here&#;s a handy table to help you choose the right film gauge for your most common items:
Product
Recommended Gauge
Small electronics (phones, etc.)
60-75 gauge
Food trays
60-75 gauge
Books or papers
60-75 gauge
DVDs
75-100 gauge
Clothing
100-150 gauge
Heavy machinery parts
150-200 gauge
Remember: This is just a guide. If you&#;re unsure about the best gauge for your products, it&#;s always best to consult with a packaging expert.
There&#;s more to shrink wrap than meets the eye! Here are some key features to consider when choosing the perfect film for your needs:
Want your products to shine? Opt for high-clarity film. It acts like an invisible box, letting customers see exactly what they&#;re getting.
The seal is the superhero of shrink wrap! A strong seal keeps your products safe and secure during shipping. Choose a seal strength that matches the weight and type of product you&#;re wrapping.
Shrink ratio refers to how much the film shrinks down. A higher ratio means you can use less film to cover more, saving you money and reducing waste.
Electronics and sensitive parts can attract dust like a magnet. Anti-static shrink wrap is your friend! It helps prevent static cling, keeping your delicate products safe.
Putting the Wrap On: How to Use Shrink Film
There are two main ways to apply shrink film to your products:
The DIY Approach (Manual Shrink Wrap):
This is perfect for small businesses or occasional use. All you need is a heat gun (like a powerful hairdryer) and some muscle. It&#;s good because you can wrap anything, any size or shape.
The Time-Saving Hero (Automated Shrink Wrap):
If you&#;re a high-volume shipper or need consistent results, a shrink tunnel is your best bet. This is basically a heat chamber that shrinks the wrap quickly and evenly. It&#;s faster, more accurate, and can even be hooked up to your existing production line.

Choosing the Right Method:
The best method depends on your needs. If you&#;re just starting out or have a low volume, manual wrapping might be sufficient. But if you ship a lot of products or want a faster, more consistent process, then a shrink tunnel is the way to go.
Selecting the perfect shrink film is a delicate dance between product protection needs, budget constraints, and operational capabilities. By understanding the various types, gauges, and features, businesses can make an informed decision that ensures their products are delivered and stored in optimal conditions.

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.
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.
:
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.
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.
