Factory Customized Size Supports Printing Of Food Grade Heat Sealed Zippered Plastic Bags For Snacks

There are many types of plastic films with vastly different qualities based upon the material from which they are made. Some of the most common structures include lidding film, shrink wrap, VSP film, stand-up pouches, and specialty bags. In general, plastic film has many benefits. It is typically lightweight and resistant to contamination. Most plastic films can be printed on, helping to improve brand recognition and aesthetics. Here are some of the most common plastics used to make plastic films:

Low-density polyethylene (LDPE)

LDPE is the most inexpensive material for plastic films. It is flexible, soft, transparent, glossy, and features high resistances to moisture, tearing, and chemicals. It is most commonly found in plastic bags but is also widely used for squeezable food bottles, bread and frozen food packaging, and flexible lids.

Linear Low-Density Polyethylene (LLDPE)

LLDPE is similar to LDPE, but it features higher tensile and impact strengths and improved heat-sealing qualities. LLDPE the highest flexibility of the polyethylene sheeting varieties. In the food and beverage industries, it is largely used in bottle caps and shrink wraps.

Ultra Low-Density Polyethylene (ULDPE)

ULDPE is a soft thermoplastic that has superior low-temperature flexibility and flex crack resistance. ULDPE has high optical clarity and is tear-resistant. It is used for cheese, meat, and coffee packaging.

Medium-density polyethylene (MDPE)

MDPE is not as commonly used as the other forms of polyethylene flexible plastic sheeting. However, it is stronger and more resistant to tears, punctures, and chemicals than LDPE and is oxygen permeable. MDPE is used for packaging baked goods, heavy-duty produce bags, wash bottles, and dispensing bottles.
