Things to Know Before You Buy Shrink Wrap Bags
If you are planning to invest in shrink wrap bags for your packaging needs, this post is for you. Shrink wrap bags are used for a wide variety of applications, such as crafts, printing, publishing, manufacturing, etc. They are perfect for both high and low-output operations and offer a wide range of benefits. PVC and polyolefin shrink wrap bags are the most common type of shrink-wrap bags. Let us see some important things to keep in mind when you buy shrink wrap bags.
Benefits Offered By Shrink Wrap Bags
- One seal required: Shrink wrap bags have only one open end, which needs to be sealed. This offers much more efficient packaging for smaller operations with only an I-bar sealer. Normal shrink films require three sides to be sealed, which is achieved by L bar sealers. However, these cannot be used for small operations. Hence, most retailers buy shrink wrap bags for smaller operations. They help reduce the hassle and also the time spent making seals.
- Offer consistent fit: Choosing the right size bag for your product will offer a consistent fit every time, which helps increase the packaging appeal to your products by allowing a tighter and uniform fit. So make sure you consider the size of your products when buying shrink-wrap bags.
Types of Shrink Wrap Bags
- PVC is the most common type of shrink bag used. It is a versatile material that offers many benefits. The film becomes harder and crinkly after heat is applied. It provides a high shrinkage. These bags are used for a variety of products. Products like gift baskets, magazines, CDs, DVDs, books, homemade soap, chocolate boxes, etc. Shrink wrap bags offer several benefits, like efficiency and appearance. However, they cannot be used as food products.
- Polyolefin shrink bags are another popular type of shrink wrap bags that offer certain advantages over PVC bags. The most important benefit is their ability to come in direct contact with consumable products. Hence, many confectioners and bakeries use polyolefin shrink-wrap bags. These bags have a different consistency than PVC bags. They are softer since they do not contain chloride. They also give off less odor when sealing and applying heat.
Cost
Cost is a major consideration when buying shrink-wrap bags. Both types of shrink bags are affordable compared to other packaging options. However, the exact cost will depend on the size and quantity ordered. PVC shrink-wrap bags are more affordable than polyolefin bags.
Know How to Use Shrink Wrap Bags
- Choose the right size shrink bags and place the item inside
- First, seal the open end of the shrink-wrap bag.
- Then, carefully start to heat the bag evenly with a heat gun. Make sure you do not apply too much heat in one area for too long, as the bag can split.
- Once the shrink bag is drawn down fairly close to the item, start to apply heat to areas that need to be tightened up a bit, until the bag is as smooth as possible, but without causing it to burn.
Conclusion
Shrink wrap bags are a worthwhile investment if you choose the right ones by considering your packaging needs. You can choose PVC or polyolefin shrink bags based on your budget and requirements.
