Poly tubing and bags are used in a variety of packaging applications all around the world. Polyethylene abbreviated PE, is the most common plastic in the world. Polyethylene is classified based on density. Three common polyethylene classifications are High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), and Linear Low-Density Polyethylene (LLDPE).
All of our polyethylene bags and tubing are made from Low-Density Polyethylene. LDPE is used in a variety of products but is preferred in some packaging films for a variety of reasons. LDPE offers low cost, easy processing, and a great moisture barrier.
Another reason Low-Density polyethylene bags and tubing are preferred is because of low sealing temperatures. Other benefits to Low-Density bags and tubing are clarity, high elongation, and softness. The high elongation makes LDPE great for resisting punctures and tears.
Customers wrapping and protecting heavy pointed objects can get very thick bags or tubing to ensure product protection. Many customers wrapping knives, nails, screws, and other pointed objects can use a 6 mil bag or tubing to protect and package their products. This ensures excellent puncture resistance without sacrificing clarity.
Polyethylene tubing and bags can be closed using a variety of methods. Many businesses use staples to close bags and tubing. Another common closure method for poly bags is the use of twist ties. The most common form of closure for both poly tubing and poly bags is heat sealing the ends. Small output operations often use impulse sealers to obtain an airtight seal to protect products from moisture and other exterior elements.
