In a previous article, Ethylene Vinyl Acetate - EVA, we mentioned the new material EVA which is extremely popular at present. EVA has many practical features and advantages compared to other traditional materials such as PVC or polyethylene, etc.

This new material EVA provides new solution to ice bags - EVA ice bags.

Most plastic retail bags are made out of polyethylene - either low or high density polyethylene. The problem is, if you put a typical polyethylene bag in the freezer, it'll start to crack and leak.

On the contrary, the EVA material has its advantages, such as good barrier properties, low-temperature toughness, stress-crack resistance, hot-melt adhesive waterproof properties, and resistance to ultraviolet radiation. Ethylene-vinyl acetate (EVA) can be processed like a plastic, but is very flexible. When EVA added to the plastic in an ice bag, EVA increases its toughness in low temperatures and resistance against cracking. This keeps your ice bags from leaking, even in very low temperatures.

EVA material thus becomes a very popular special additive in making EVA ice bags that give extra strength and durability to ice bags.

Some EVA ice bags manufacturers are Rui Heng Yi Yang International Trade (Beijing), Ice Bags HQ, etc.
