There are two main ways to categorize plastic bags: by the type of plastic used and by the design o | |
Plastic bags are a form of polymers. Depending on various factors of the polymer used in manufacturing the plastic bags, they are classified into four main categories. Let us discuss these categories in details; they are as follows: 1. High-Density Polyethylene (HDPE) HDP is the most commonly used variant of plastic bags in most parts of the world. They are water and temperature resistant, lightweight, relatively transparent and high in tensile strength. These bags meet the USDA and FDA food handling guidelines. 2. Low-Density Polyethylene (LDPE) They are completely transparent, thus ideal to be used in commercial kitchens. The common applications of LDPE bags are food bags, bread bags, and utility bags. They have a medium strength and stretch properties. 3. Linear Low-Density Polyethylene (LLDPE) LLDPE has a thinner gauge as compared to LDPE. But there is no much difference in strength between LDPE and LLDPE. Thus consumers can have the same quality at a lower price by purchasing the LLDPE plastic bags. They are mainly used as plastic shopping bags. 4. Medium Density Polyethylene (MDPE) The transparency of MDPE plastic bags lies between that of HDPE and LDPE plastic bags. They are the least stretchable plastic bags, and also they have poor strength. This makes unsuitable to carry or store bulk products. They are used to pack lighter products and as garbage bags. 5. Polypropylene PP stands unique by their property of great chemical strength and resistance. This is the only variant of plastic bags that is non-breathable. Therefore, they have a longer shelf life and are used to pack herbs, nuts, candies and other confectionaries. | |
