High-temperature hyperbaric bactericidal – spout retort pouch need to be sterilized (121-125 degrees Celsius) in a closed environment in sealed high-pressure high temperature sterilization equipment in 30-45 minutes boiling with no external pressure (100 degrees) can cause soft packing drums to cause damage bags. If the sterilization temperatures are not enough, it will cause inflation of bag. Therefore, the high-temperature sterilization device must meet the product sterilization process requirements and cooking bag sterilization conditions to be set, properly used.
Sterilization Process Test – Different contents of content conditions are different, so it is necessary to set the temperature, time, temperature rising and falling curves of the sterilization kettle according to the actual product contents to achieve killing the fungi, viral spores thoroughly. If a soft package swells in the shelf life, but there is no leakage, it is basically certain in some product sterilization process, due to the lag of the placement and sterilization of sterilization, it is not completely. This needs to require customer to readjust the high temperature sterilization process.
Shelf-life test / Aging test – Customers need to judge the actual optimal quality and longest shelf life of the soft package through the actual aging test, which is generally the simulation of 40 degrees Celsius and more than 70% or more high humidity. Soft packaging products. The sterilization process needs to be re-adjusted if it does not pass the aging test.
Physical performance testing conditions – soft packaging is not traditional hard metal cans, even if it is fully sterilized, due to storage, logistics, shelves, customers, there will be soft packaging, leakage, puncture, pressure, etc. The situation is required to set the physical mechanical performance detection after the full-mode packaging conditions in which sufficient simulated shelf-life conditions. Our standard factory inspection project mainly: composite intensity (peeling force detection), heat sealing strength (disconnection detection), pressure detection, drop detection, cooking test, penetration test, gas chromatography, oxygen detection etc.
Packing softness and quite wide – soft packaging products have a big difference in softness and quite a wide range of different contents products: three-sided vacuum packaging requires better softness to better reach vacuum preservation; There is a certain amount of softness in the bag to have a certain amount of softness; the nozzle bag is more considered to be a quite gang of the bag for easy pouring liquid content. These are all more enhanced options that we make materials and process improvements based on customer product conditions and their usage requirements, more targeted to meet different selection tendencies of different customers.
