There are many types and sizes of poly bags in the market, and they are everyday items that we almost get in contact with daily.
Our food, clothing, and cleaning items are presented to us protected from the elements in a poly bag.
Depending on the industry or final purpose, the way the bag is sealed makes an essential attribute with its differences, Let’s take a look at a few of the most popular poly bag seals and what different seals are used for, so you can decide which option might be best for your application:
1. Zip Seal Reclosable Poly Bags
02
Fold and Adhesive Poly Bags
As one of the most cost-effective poly bag seals, the fold and adhesive poly bag seal is a popular choice. An extra lip of material extends beyond the bag opening, which is folded over the bag to close.
A fold and adhesive poly bag seal is ideal for packaging items that need protection from dirt or debris but aren’t meant to be airtight or puncture resistant. They are commonly used for packaging items like clothing or fabric or can even be used as temporary storage for food items.
03
Twist Tie Poly Bags
This type of poly bag seals with a thin, flexible wire or ribbon which wraps around the bag opening and twists or ties to secure. The poly bag is open on one end and heat-sealed on the other. It’s commonly used for packaging food items such as bread, potatoes, or loose bulk cereals and grains.
04
Drawstring Reclosable Poly Bags
Drawstring reclosable poly bag seals use a simple cotton rope threaded through a heat-sealed tube at the opening of the poly bag. To close, the ends of the rope are pulled tight. To open, the rope slides back into the tube as the opening expands.
One advantage of drawstring reclosable poly bag seals is that the rope closure can double as a handle for easy transport. This reclosable poly bag seal is often used for packaging ice, as it can be easily accessed and reused.
