Heavy Duty Zip Lock Bags - 50µm and over

Need some resealable bags that are a bit more durable or puncture-resistant?


Frequently Asked Question

Are your zip lock bags food grade?

Yes, our zip lock bags are made from virgin LDPE material, so they are perfectly safe for food storage.

What is the difference between polythene (LDPE) and polypropylene?

Polythene is more translucent (cloudy) than polypropylene. This is really important for light-sensitive goods, such as old comics, books and photos. Polythene is also smoother and more flexible than polypropylene, which will crinkle more easily. Again, when it comes to collectables, this can be important as crinkly material can potentially scratch them. Our heavy duty zip lock bags are made from polythene, but we also have some peel & seal polypropylene bags if you are looking for resealable bags for display purposes.

What are some other names for zip lock bags?

Zip lock bags are also referred to as resealable bags, zip seal bags, clickseal bags, press seal bags or self seal bags.
