PLASTIC BAGS
Plastic bags are not created equal because the are meant for different purposes.

Bags or pouches are a type of packaging for containing frozen food, fresh produce, snack foods, hardware, gardening products, etc. They are often made from a single roll of film on a horizontal or vertical form-fill-seal machine.

Several design options and features are available. Some bags have gussets to allow 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 onto some.

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

Plastic bags usually use less material then comparable boxes, cartons, or jars, thus are often considered as "reduced or minimized packaging". Depending on the construction, plastic bags 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.[1] If disposed of improperly, however, plastic bags can create unsightly litter and harm some types of wildlife.

Bags are also made with carrying handles, hanging holes, tape attachments, security features, paper and other laminations, heavy sacks, pouch and standup pouch and other shapes. Some bags have provision for resealable closing; others are sealed, often by heating the open edge, once filled, and can only be opened by destroying the packaging.

Open bags with carrying handles are used in large numbers worldwide. Stores often provide them as a convenience to shoppers: Some stores charge a nominal fee for a bag.

Heavy duty mulitple-use shopping bags are oten considered environmentally better than single-use paper or plastic shopping bags. When possible single-use bags should be recycled or reused as trash bags, storage bags, etc. Responsible solid waste usage is encouraged. Used bags should not be littered: this can be unsightly and damage wildlife.
