Common Plastic Bagging Materials

Common Plastic Bagging Materials

Plastic bags are something that we often take for granted within our everyday lives. From our trash bags to zip-locked bags and laundry bags to custom print bags, plastic bags play a crucial role in all of our lives. But most of us don’t care to learn about plastic bags, let alone the materials that are needed to make them. You may be surprised to learn that each and every plastic bag you have in your home is made out of different materials. 

Most of us believe plastic bags are an all-size-fits-one. This could not be further from the truth. Each and every plastic bag you’ve ever used has had its own distinct size and material. Some are more durable than others, while some are able to hold more objects than others. Every bag is different because of the material that is used to create them. Here are some common plastic bagging materials. 

Low-Density Polyethylene Plastic 

Low-Density Polyethylene Plastic, known for short as LDPE, is the type of material that is used primarily for plastic bags that are utilized for food packaging and preservation. Usually, LDPE bags have a low melting point and are actually ideal for heat sealing. These bags are primarily used for food packaging, utility bags, and even trash bags. They can even be made into bubble wrap, garment bags, foams, and especially produce bags. 

High-Density Polyethylene Plastic Bags 

On the opposite side of Low-Density Polyethylene is High-Density Polyethylene plastic bags. These bags are some of the most common plastic bags in the entire world. HPDE bags feature chains of straight molecules that are incredibly linear. This results in a bag that has polymers with minimal to no bracing. HPDE bags are mainly utilized as utility bags, trash bags, and even garbage bags. You will find these bags in office waste, restroom waste, and shredded paper. Even though they are not used primarily for produce, HPDE bags can also hold food packaging and materials. 

Medium Density Polyethylene Plastic Bags 

Caught in between LPDE bags and HPDE bags are Medium Density Polyethylene plastic bags. This is the perfect mixture of both LPDE bags and HPDE bags. MDPE bags have common attributes of both LPDE bags and HPDE bags, such as the fact that MDPE bags are not opaque like HPDE material but not as clear as LPDE bags. These bags are also known for their strong chemical resistance but are not dense enough to hold immense and robust material. 

Conclusion 

Ultimately, no plastic bag is the same when it comes to the materials that they are made of. Whether you need something dense and strong for an abundance of items or you need something slim and simple to throw your trash in, the type of plastic bagging material is incredibly important to what kind of plastic bag you need to purchase. Try remembering all of this the next time you use a plastic household bag.
