LDPE Bags for Economical High Quality Package

Polyethylene is a material that is used for more than half of all films, and low density polyethylene (LDPE) is the source of most poly bags. LDPE is soft, stretchy, and water and air proof. Polyethylene is delivered in the form of small resin pellets or beads. By a process called extrusion, the hard beads are converted into bags of plastic.

LDPE plastic bags have become popular, because they are low cost in high quality packaging to manufacture and quick lead times in manufacturing, which up until recently was relatively inexpensive, making them an economical way to package goods. They are excellent moisture protection and flexibility in size, colors and style. Cost effective from the product packaging and display items of interest.

LDPE bags come in various sizes and styles. Some basic polyethylene bag understanding will help you determine the best bag to fit your business needs.

Styles of polyethylene bag include flat poly bags, gusseted polypropylene bags, zip lock polyethylene bags and many more. Flat bags are two dimensional, while gusseted bags expand to add the dimension of depth. Polyethylene bags offer a clear view of their contents, but a dash of color can live or enhance the inner product.

Decide Polyethylene Mil Thickness

• Lightweight 1 or 1.25 mil: Great for economical packaging and coverage of lightweight products.
• 1.5 or 2 mil: These are the most commonly used thickness for storing, shipping, or displaying everyday items.
• Heavy-duty 3 or 4 mil: These bags are capable of protecting and supporting heavy and abrasive items.
• 6 mil: These are the toughest bags, offering total protection for the heaviest products.

When check bags, remember that polyethylene is very flexible and the gauge can only be measured accurately with a poly micrometer.  Machine micrometers, intended for less sensitive materials, pinch and flatten bags or film.

Summary

Low density polyethylene is one of the most widely used packaging materials in the market. It is low in cost compared to wood and metal. It very tough, flexible, a barrier to moisture, chemical resistant, and light weight. 65% of the LDPE used in the world is for films and sheets to make garbage bags, grocery sacks, garment bags, shrink film, stretch film, pond liners, construction and agriculture film and food packaging. Grocery sacks made of LDPE are soft and do not have a “rustle” sound. They are transparent. Fresh produce bags are sometimes made out of LDPE.
