Why is Film Thickness Important?

Plastic films are often used to encapsulate, protect and preserve products that are sold to consumers or industry. The film is used as a two-way barrier to stop product leaking out and also external contaminants from migrating in.

The effectiveness of the film as a barrier is related to its chemical composition and also its thickness.

Films which are below a specified thickness may fail physically- bursting, splitting or leaking, they will also be less effective at stopping the migration of oxygen and contaminants that can lead to product spoilage.
