Aseptic Bags Oxygen Transmission Rate Tester March 20,2019.

Aseptic bag is a kind of packaging material produced by polyethylene particles as raw material, blown film, cutting, heat sealing, vacuum packaging, sterilization in a clean environment.

Aseptic bags are widely used in aseptic solid raw materials, sterile pharmaceutical auxiliary materials, sterile preparations and the like due to their sterility, non-toxicity, excellent low-temperature resistant performance, good chemical stability and electrical insulation properties. Transit and temporary storage of pharmaceuticals and chemical products.

In addition, in the food industry, aseptic packaging bags are divided into high volume aluminum-plastic composite aseptic bags (5 ~ 200L) and low volume co-extruded film aseptic pouches (200 ~ 500ml); aseptic bags can also be used with cardboard The paper-based multi-material composite packaging containers, which consist of aluminum foil and food, contain about 20% of the entire packaging weight, and mainly block the effects of liquid leakage and microbial invasion. They are perfect packaging materials for juices, jams, dairy products and other foods.

How to choose high quality Aseptic bags for your products package.Oxygen transmission rate is one of the key point for choosing aseptic bags.

What’s the definition of GTR?

Gas transmission rate (GTR) is the measurement of the amount of gas (O2, N2, CO2 etc)that passes through a substance over a given period. It is mostly carried out on non-porous materials, where the mode of transport is diffusion, but there are a growing number of applications where the transmission rate also depends on flow through apertures of some description.

What’s the application of GTR on industries?

On industries, many kinds of materials need to test gas transmission rate for protect the foods, medicine etc. Therefore, Some testing instruments are widely used in food industry, pharmaceutical industry, cosmetics flexible packaging materials industry (plastic film, barrier materials, sheets, metal aluminum, PVC, PVC sheets), college, university and quality institution for gas(O2, CO2, N2, non-inflammable gas and non-corrosive gases) permeation test and quality control.

So how to test GTR of packaging materials for your product?

Gas Permeability Analyzer can help you to solve it!! Gas permeability analyzer is to test the gas (O2, N2, CO2 etc) transmission rate (GTR) of films and sheets materials.
