PEVA (polyethylene vinyl acetate) and PVC (polyvinyl chloride) are two types of plastic materials that can be used to make corpse bags. PEVA is a non-chlorinated plastic and is considered to be a more environmentally friendly alternative to PVC, which contains chlorine.

In terms of their properties, PEVA is generally softer, more flexible, and has a lower melting point compared to PVC. PEVA is also more resistant to UV light and can withstand cold temperatures better than PVC. On the other hand, PVC is generally more durable and has a longer lifespan than PEVA. It is also more resistant to chemicals and oils compared to PEVA.

When it comes to using these materials for corpse bags, both have their advantages and disadvantages. PEVA corpse bags are considered to be more eco-friendly and safe for the environment, but they may not be as durable as PVC bags. PVC bags may be more durable, but they may release harmful chemicals when incinerated, and are not as eco-friendly as PEVA bags.

In summary, the choice between PEVA and PVC for corpse bags depends on the specific requirements and preferences of the user. Both materials have their pros and cons, and it is important to consider factors such as durability, environmental impact, and safety when making a decision.
