Best Manufacturer of Hot Wire Bottle Cutter in India
The plastic films are one of the most preferred modes of packaging of different products. The plastic films are strong, and they also offer the best safety to the products from the outer environmental such as moisture, dust, etc. The plastic films are also best for the packaging of products as they do not allow the moisture to enter the packaging of the products. One of the major problems that are faced by the plastic films is the puncture of the films due to impact from outer sources during transportation or storage. This can damage the packaging and cause damage to the products also.
The puncture resistance of a plastic film is the amount of force that plastic films can bear when applied to it from an external hemispherical indenter without failure. The manufacturers of the packaging materials need to ensure that the packaging products that they manufacture for different products are of best strength and for that, they need to test the puncture resistance of the plastic films with great accuracy. The testing procedure is conducted as per the guidelines are given in the ASTM D 2582.
There are many different factors that responsible for the puncture resistance of the plastic films. The manufacturers need to take these factors into account while choosing the materials for manufacturing of the packaging pouches.
Factor affecting the puncture resistance of plastic films
The material that is used for manufacturing of different types of plastic films is one of the major factors that affect the puncture resistance of the plastic films. Different materials such as LDPE, polyethylene, and many others can cause an increase of decrease in the puncture resistance of the plastic films.
Melt flow index of the resins
The resins that are being used for the manufacturing of the film also has a great impact on the puncture resistance of the plastic films. The manufacturers need to ensure that the resins that are being used for manufacturing of the film have the optimum value of the melt flow rate so that best value of puncture resistance of the products.
To assure the best quality of packaging products, the manufacturers must test the puncture resistance of plastic films. The presto’s puncture resistance tester is a highly efficient testing instrument that is used for evaluation of the puncture resistance of the plastic films and then ensures the best strength and quality of packaging bags and pouches.
