Bag types Packages
Plastic bags of gardening supplies 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 sealing machine.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
onto some.
Plastic bags usually use less material than 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. 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, etc. Some bags have provisions for easy and controlled
opening. Reclosable features, including press-to-seal zipper strips such as
Ziploc, are common for kitchen bags. Some bags are sealed and can only be
opened by destroying the packaging, providing some tamper-evident
capability.
Bags can be made with a variety of plastics films. Polyethylene (LDPE, LLDPE
etc) is the most common. Other forms, including laminates and coextrusions
can be used when the physical properties are needed.
Boil-in-bags are often used for sealed frozen foods, sometimes complete
entres. 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.
Porous bag for cooking riceBag-In-Box packaging is often used for liquids
such as wine and institutional sizes of other liquids.
Plastic shopping bags
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 reusable shopping bags are often
considered environmentally better than single-use paper or plastic shopping
bags.
Trash bags or Bin bags
Flexible intermediate bulk container
Flexible Intermediate Bulk Containers (Big bags, bulk bags, etc.) are large
industrial containers, usually used for powders or flowables.
Danger to children Thin plastic bags, especially dry cleaning bags, have the
potential for causing suffocation. About 25 children in the United States
suffocate each year due to plastic bags, most under the age of one. This has
led to voluntary warning labels on some bags which may pose a hazard to
small children.
