Tear testing has been performed for more than a half century to measure the mean internal resistance of substrates to the propagation of a deliberately initiated tear to determine its dynamic resistance. Protective coverings are commonly used as for various products and plastics film is normally used as the material. Often, these low peel force films are used to protect LCD screens and other scratch-prone surfaces. The force required to remove the film is very important for both the consumer and the manufacturer. The film must be easy to remove, yet the bond must be strong enough to remain intact for product security. Some of the most common test types within plastics testing are tensile strength, elongation to break, yield strength, modulus, Poisson’s ratio, compression, flexural, shear and friction. Saicheng provides a large quantity of equipment for our packaging quality control. We appreciate Saicheng’s contribution in the construction of the testing laboratory.

At Atlantic, we specify high quality, high performance films that are engineered with ultimate load holding force and are also very consistent . Because of the testing we perform in the Film Lab, we can illustrate these film properties with data. With our specialized stretch film testing equipment, we participate in the development of new stretch films, working not only with film manufacturers but also with the producers of the resins used to fabricate stretch films. The ASTM D638 standard is defined as a testing method to determine the tensile strength of both reinforced and non-reinforced plastics. This protocol is performed on “dog bone” shaped samples and under different pre-treatment, temperature and humidity conditions as per the different speeds of the testing machine. Hot tack strength (the force to measure seal-strength while the film is still semi-molten) is too low, the film will not perform or run properly during the filling operation and the package may leak product after it is filled.
Perhaps the most critical feedback is repeated sales items in the new package. The consumer responses are treated qualitatively for feedback into the new packaging process. Some types of package testing do not use scientific instruments but use people for the evaluation. When a final package design is complete, the specifications for the component materials needs to be communicated to suppliers. Packaging materials testing is often needed to identify the critical material characteristics and engineering tolerances.

In this regard, the ASTM D638 protocol is related to the ISO test, since the purpose of both is to demonstrate the resistance of a plastic to tensile forces. However, in its website, ASTM clarifies that the technical content of both tests is different, and therefore they are not interchangeable. The companies that are required to measure this parameter usually perform just one of the tests, with the ASTM testing method being the favorite in the North American market and area of influence.
The whole idea of packaging materials for the products is not leaving the products uncovered and unprotected. As these products are stored or transported, they need to be stay protected from factors that may affect the integrity and safety of the products like the extreme forces that act upon them during handling. There are differences forces with different amplitude acting upon the products during different stages of delivery right from the storage to the transportation. These instruments can easily assess different aspects of their quality and give information about which aspects of quality need attention and can be improved.

Different weights are used in the pendulum for defining different weight scales. A pointer is also given to the pendulum which helps in taking accurate readings and test results. This paper presents the development of a method to measure damage to packaging laminates by penetration. A hemispherical probe was shown to provide the most reproducible results and the rate of loading was found to be a small factor. It was shown that the presence of paper in the structure has a decisive effect on puncture resistance. For paper-based laminates, the paper layer limits the strength by rupturing first and then producing premature rupture of the other layers; the result is a 4-10-fold improvement in strength by eliminating paper as an outer layer. For laminates without paper, all layers rupture together so changing the composition of the non-paper layers has a direct influence on the puncture resistance. The direction of the penetration through the laminate usually has an effect on the energy to puncture.
