Polyester film is a stretched form of polyethylene terephthalate (PET) and is used for its high tensile strength and many distinct properties. It is used in manufacturing a wide range of products such as packaging foils, protective covering over maps or books, insulating material for houses, etc. Among all these applications, one common product of it is the plastic shopping bag. These bags tend to experience a lot of tension on its surface due to prolong hanging and carrying heavy stuff. Hence tensile testing holds a major importance for shopping bag manufacturers. Also, it is equally important to perform the test on a standardized tensile testing machine.

The Tensile Test Procedure

The test samples are cut into a “dog-bone” shape, from which one end will be fixed and the other end pulled with increasing force until the sample breaks apart. Tensile strength is calculated in force/cross-sectional area so that an accurate comparison can be conducted on different samples.

It is also useful to know the amount of deformation a material will undergo during a tensile test. This is known as strain and is calculated as the change in the length of a portion of the sample divided by the original length.

But prior anything else one must ensure that the tensile testing machine complies with required standards. Also for a user-friendly experience, you can go for a model offering a variety of advanced features. Use of technologically advanced instrument can bring precision in your work.
