Permeation is the movement of gas or vapor molecules through a barrier. It is driven by the permeant concentration gradient from the permeant’s high concentration side to the low concentration side. The permeation of a material is measured by testing the transmission rate with an analyzer.
measure the gas or vapor molecules that transmit through the barriers under controlled conditions. This data gives you the ability to understand if your barrier or film will protect your product for a specific application. Better barriers have lower transmission rates providing better protection. We offer oxygen, carbon dioxide, and water vapor permeation analyzers. The permeation analyzers can measure gas permeability for products in a wide variety of industries and applications. Permeation analyzers can be used to test films, trays, bottles, pouches, cups, pods, caps, containers, blister packs, electronics and more. Our analyzers can test a variety of materials including polymer films, coated paper and paperboard, cartons, coated films and laminations, foils, multi-l
Evaporated Residues Tester can test the dissolving-out amount of test sample soaked in specified liquid. Applicable to tableware, food containers, packaging films, bags, cap sealing rubber pad, painted coating for inner wall of cans or tins, plant fiber container and so on made from polyethylene, polystyrene, polypropylene, perchloroethylene resin, epoxy novolac, etc.; also applicable for some chemical reagents.
specially designed considering tensile testing requirements for flexible materials that are commonly used in product packaging to study different properties of materials.
This instrument utilizes the latest embedded control system and operating software, with user-friendly operating interface and intelligent data management system.
The tensile testing equipment can be used to perform a different types of tests like traction, stripping, sealing, tear, compression, bending, and cutting strength of plastic film, composite film, plastic tapes, soft packaging material, rubber sheets, paper, non-woven fabrics and other packaging materials, widely used in industries related to production of plastic films, packaging, pharmaceuticals, food, inspection agency, research institutes etc. to study properties of materials and finished products.
The is the testing equipment that is used to measure the cofficient friction of materials. There are basically two different kinds of frictions available for packaging testing. The plastic sheets, papers, films, etc. are some materials that will be used to determine its coficient friction. If you are searching for reliable and affordable lab testing equipment then we recommend you to purchase it from Presto Group. This testing machine is effective to determine the coefficient friction.
Introduction about coefficient of friction
The Coefficient Of Friction is considered to be the value that will help to determine the connection between two objects which are involved in testing. It is also considered to be the value that is used in physics to find the normal force of a particular object when other methods are unavailable.
The coefficient of friction is either based on a dynamic value or the static one. But it is a dimensionless quantity that does not have any unit. Besides this, it is a scalar component that does not contain any other physical quantity.
It will depend on the objects that are causing the friction. Therefore you Can make use of the lab testing equipment to determine its value on different materials. Many people have this misconception that the value of this friction is limited to the values between zero and one. This usually means that the friction force is stronger than the normal force.
The Coefficient Of Friction Tester manufactured by Presto is considered to be the best device to determine its value on different materials. Thus, you can easily purchase it from us at affordable prices.
Now, you get the idea about the coefficient of friction. Let us now focus on the uses of testing its value.
