Plastic bags or pouches are a type of packaging for containing frozen food, fresh produce, snacks, hardware, etc. They are generally made from a single roll of film on a horizontal or vertical form fill sealing machine.
They can be using a variety of different plastic films. Polyethylene, or 'polythene', of various grades and types, is the most common. Other forms, including laminates and co extrusions can be used when the physical properties are needed.
There are many design options and features available. Some bags are gusseted to allow a higher volume of contents. Some can stand up on a shelf or a refrigerator. Others have a simple plastic ridge that clicks shut and pulls open for continual re-use.
Bags can also be made with carrying handles, hanging holes, tape attachments, and security features. Some are sealed and can only be opened by destroying the packaging, providing some tamper-evident capability.
