  • Keep the container closed and the contents confined for the duration of the designated shelf life.
  • Prevent the product from being opened prematurely.
  • Create a barrier against dirt, oxygen, and moisture.
  • Permeation control is crucial for a wide variety of products: meals, chemicals, etc.
  • Provide a mechanism for reusing or reclosing the container.

These variables are shared between sister functions inside the same enclosing scope; hence closures are vital.

What Is A Food Seal?

A closure can be described as any means of securely sealing a package in order to keep the product contained and protected.

A closure is a device that secures a product inside a pack but can be removed to provide access to the goods.
