kitchen condiment packaging bag stand up spout pouch

More and more products choose to use self-supporting nozzle bags for packaging. The convenient performance of self-supporting nozzle bags has attracted many condiment companies to love self-supporting nozzle bags. So, what properties should be paid attention to in the application of self-supporting nozzle bags in condiment packaging?
1. Barrier properties of self-supporting nozzle bags
(1)Barrier ability of self-supporting nozzle bag to oxygen in the environment. It was verified by the oxygen transmission test. If the barrier property of the packaging material is poor, the oxygen transmission rate is low, and the oxygen in the environment penetrates into the package more, the condiment is prone to mildew and swelling due to contact with a large amount of oxygen. Bags and other quality problems.
(2)The anti-rubbing performance of the self-supporting nozzle bag. It can be verified by comparing the oxygen permeability test of the samples before and after rubbing or the turpentine oil test of the samples after rubbing, so as to prevent the packaging from being greatly reduced in barrier properties under the action of external force due to poor rubbing resistance, and even air leakage and liquid leakage.
2. Physical and mechanical properties of self-supporting nozzle bag
(1)The uniformity of the thickness of the self-supporting nozzle bag. It is verified by testing the thickness of the packaging. The uniformity of the thickness is the basis for ensuring the stable performance of the packaging material.
(2)Self-supporting nozzle bag heat sealing effect. Verified by heat seal strength test to prevent bag breakage or leakage due to poor sealing effect of heat seal edges.
(3)Composite fastness of self-supporting nozzle bag. It is verified by the peel strength test that if the peel strength of the stand-up pouch is low, it may lead to delamination of the packaging bag during use.
(4)The opening performance of the self-supporting nozzle bag cover. Verified by the rotation torque test to prevent the inconvenience to consumers due to the excessive rotation torque between the lid and the suction nozzle, or leakage due to the cover and the suction nozzle not being screwed tightly.
(5)Self-supporting nozzle bag sealability. It is verified by the sealing performance (negative pressure method) test to prevent the leakage of liquid and air from the packaging of finished condiments.
3.Hygienic performance of self-supporting nozzle bag
(1)The residual amount of organic solvent in the self-supporting nozzle bag. It is verified by the solvent residue test that if the solvent residue is too much, the packaging film will have peculiar smell, and the residual solvent will easily migrate into the condiment, which will cause the peculiar smell and affect the health of consumers.
(2)The content of non-volatile substances in the self-supporting nozzle bag. It is verified by the evaporation residue test to prevent the packaging material from causing a large amount of migration during long-term contact with the condiments due to the high content of non-volatile substances, thereby contaminating the condiments.
