What performance should be focused on for self-supporting bags for jam packaging?

(1) Barrier

The barrier ability of oxygen in the environment - verified by the oxygen permeation test. If the barrier property of the packaging material is poor, the oxygen permeation amount is low, and the oxygen in the environment penetrates into the package, the jam is easy to contact. To a large amount of oxygen, there are quality problems such as mold and swelling.

Hail-resistant performance - can be verified by comparing the oxygen permeation test of the sample before and after the test or the turpentine test of the sample after the antimony test to prevent the blockage from being greatly reduced or even leaked due to the poor resistance to the external force. Gas, liquid leakage.

(2) Physical and mechanical properties

Uniformity of thickness - verified by testing the thickness of the package, the uniformity of thickness is the basis for ensuring the stability of the packaging material.

Heat-sealing effect - It is verified by the heat-sealing strength test to prevent problems such as bag breakage or leakage due to poor sealing effect of heat sealing.

Composite fastness - verified by the peel strength test, if the peel strength of the stand-up pouch is low, it may cause delamination of the package during use.

Opening performance of the cover - verified by the rotary torque test to prevent inconvenience to the consumer due to excessive rotational torque between the cover and the nozzle, or leakage due to the cover and the nozzle not being tightened .

Sealability - Verification by sealing performance (negative pressure method) test to prevent liquid leakage and air leakage in the finished packaging of jam.

(3) Hygienic performance

Residual amount of organic solvent - verified by the solvent residue test. If the residual amount of the solvent is excessive, the packaging film has an odor, and the residual solvent easily migrates into the jam, causing odor and affecting the health of the consumer.

The content of non-volatile substances - verified by the evaporation residue test to prevent a large amount of migration and contamination of the jam during long-term contact with the jam due to the high content of non-volatile substances in the packaging material.

The Labthink Packaging Safety Testing Center covers an area of ​​410 square meters and includes a barrier test area and a conventional test area. It is equipped with a full range of Labthink instruments. The testing center's testing capability approved by CNAS covers 57 kinds of testing objects and 298 testing items, such as plastics and related products. It is an instrument manufacturing enterprise with wide testing capability and many testing items recognized by China's packaging testing equipment industry. Jinan Languang Electromechanical Technology Co., Ltd. is looking forward to enhancing technical exchanges and cooperation with enterprises and institutions in the industry!
