Grip seal bags packaging guide

Type of material used in making grip seal bags

The most common types of plastics used for making grip seal bags are cellophane, polyethylene (LDPE, MDPE, and HDPE) and vinyl.

Cellophane is too weak to protect the items, but the grip seal bags made of this material are extremely lightweight.

The LDPE polythene can protect the held items from dirt, scratches and moisture. The MDPE will additionally protect items from punctures and tears. The HDPE will protect items from all of the above.

Opacity of resealable grip seal bags

Opacity can range from crystal clear to completely opaque. Opacity of the material goes hand in hand with its durability. The clearest reclosable grip seal bags are the least durable and vice versa. Clear films are used for display, while opaque are used for hiding or protecting the held items from sunlight.
