A plastic bag, Poly Bag, or pouch is a type of container made of thin, flexible, plastic film, nonwoven fabric, or plastic textile. A Plastic bag can be used for containing and transporting goods such as foods, produce, powders, ice, magazines, chemicals, and waste. It is a common form of packaging.

• We have an extensive range of clear polythene bags varying in width from 2" (50mm) to 48" (1220mm).
• These bags are normally stocked in multiple thicknesses - 120g (light duty use), 250g (medium duty use) and 500g (heavy duty use).
• If you are unsure of the gauge that you require, please see the below chart as an indication of bag durability.

This type of plastic bag can be heat sealed together. Some other types of plastic bag are bonded with adhesives or are stitched.

Several design options and features are available. Some bags have gussets to allow a higher volume of contents. Some have the ability to stand up on a shelf or a refrigerator. Some have easy-opening or reclosable options. Handles are cut into or added into some.

A Poly bag can be made with a variety of plastics films. Polyethylene (LDPE, LLDPE, etc.) is the most common. Other forms, including laminates and co-extrusions can be used when the physical properties are needed.

Poly bags usually use less material than comparable to boxes, cartons, or jars, thus are often considered as "reduced or minimized packaging".

Depending on the construction, a plastic bag can be well suited for plastic recycling. They can be incinerated in appropriate facilities for waste-to-energy conversion. They are stable and benign in sanitary landfills. If disposed of improperly, however, plastic bags can create unsightly litter and harm some types of wildlife, so remember to recycle!

Bags are also made with carrying handles, hanging holes, tape attachments, or security features. Some bags have provisions for easy and controlled opening. Re-closable features, including press-to-seal zipper strips, are common for kitchen bags bought empty and for some foods. Some bags are sealed for tamper-evident capability, including some where the press-to-reseal feature becomes accessible only when a perforated outer seal is torn away.

Boil-in-bags are often used for sealed frozen foods, sometimes complete entrees. The bags are usually tough heat-sealed nylon or polyester to withstand the temperatures of boiling water. Some bags are porous or perforated to allow the hot water to contact the food: rice, noodles, etc.

Bag-in-box packaging is often used for liquids such as box wine and institutional sizes of other liquids.
