Influence and control of shrinkage machine bag size deviation

- Apr 07, 2019 -

With the maturity of the domestic plastic soft shrinking machine packaging market, the market competition is becoming more and more fierce. In order to meet the needs of market development, plastic composite shrinking machine flexible packaging enterprises in addition to further strengthen the quality control of printing, compounding and other processes, but also pay more and more attention to the quality of bag making.

Bag making processing is the latter process of the production and processing of plastic composite shrinking machine flexible packaging. If the quality of the bag making is unqualified or the consumption is too high, then the light will cause the previous processes to be abandoned, and the heavyweights will be rejected by the downstream customers of the shrinking machine. Production and operation have a major impact. In the quality control of bag making, the dimensional deviation of the bag (such as length deviation, width deviation, etc.) is an important technical index that affects the overall beauty and use effect of the composite shrinking machine bag, and is also an indicator that the shrinking machine customer attaches great importance to.

Information on the shrinking machine solution:

The basic process of thermal phase separation in a shrinking machine factory means that the heat shrinking machine heats the polymer in a high boiling point, low volatility solvent medium at a high temperature, and forms a heat shrinkable machine homogeneous liquid. Then the heat shrinking machine cools down, thereby causing the solution medium to be produced-solid phase separation, or liquid-liquid phase separation, and then using a heat shrinking machine volatile reagent to extract the high boiling point of the solvent, and then drying after a predetermined time.
