U.S. Packaging and wrapping is happy to announce a new line of stretch film that offers superior load retention at an affordable price. The new Eco-Wrap stretch film is made with a new technology that allows the stretch film to stay stiff and clear allowing users to downsize on thickness and save on cost. We […]

Aluminum Foil Basics

This is a quick post to help inform our readers and customers about different aspects of aluminum foil. Not specifically the aluminum foil rolls and aluminum foil sheets we sell, but all aluminum foil in general. Aluminum is made from bauxite. From the bauxite a powder called aluminum oxide is produced. The aluminum oxide has […]

What is Tear Strength?

Tear strength is simply the force it takes to rip a plastic film. Tear strength is commonly used for testing stretch film and other plastics. An Elmendorf tear test is commonly used to find the tear strength. One end of the sample stretch film is held in a fixed clamp and the other end is […]

What is Tensile Strength?

Plain and simply, tensile strength is the ability of a material to resist a direct pull. When referring to ultimate tensile strength, it is the maximum stress that can be withstood before breaking. Commonly the tensile strength is expressed in pounds per square inch. Higher tensile strength is generally preferred for a variety of packaging […]

PVC Shrink Wrap

PVC Shrink wrap is derived from Poly vinyl chloride. PVC is a plastic that differs from polyethylene because it has a chlorine atom in place of a hydrogen atom. Alone, the PVC found in PVC shrink wrap is hard and brittle. PVC also has a low thermal stability that starts as low as 212 degrees […]

Stabilizing Unit Loads With Stretch Film

It is important for unit loads to be stabilized during shipping and handling. Stabilization helps to maintain load geometry, therefore reducing product loss and increasing safer handling. For many heavy loads a polypropylene strapping is used. When strapping products, it is important to be sure the strapping does not cut into the product container. Strapping […]

Shrink Tunnels & Shrink Wrap Machines

This is the last post in a series that is focused on a few different machines used in the shrink wrap process. So far our series has covered heat shrink guns, I-Bar sealers, and L-Bar sealers. We are now going to focus on the shrink tunnel and how it can benefit a shrink wrap operation. […]

L-Bar Shrink Wrap Machines

Our last post was focused on I-Bar shrink wrap machines. We went over the basics of I-Bar shrink wrap machines. This series is by no means intended to be a detailed look into shrink wrap machines. We are simply trying to point out the mere basics to help people when they are considering purchasing shrink […]
