Food packaging manufacturer: high-temperature cooking bags of testing work

A packet from order, design, printing to bag to finished product, and then to the delivery of the goods, so there is a check in the process of the work through each link. High temperature cooking bags, then, what need to be test? In order to make everyone better operating, we summed up for everybody, to share the following: 1, high temperature cooking bags, raw material inspection: a. The thickness of the film, the tensile strength, tension, wetting the air/moisture permeability, high temperature resistance, health fitness, appearance. b。 High temperature resistance of adhesive, printing ink, food hygiene, fit. 2, thin film composite process check: a. Appearance ( No obvious defects such as wrinkling, abscission visual) ； b。 The viscosity of compound speed, glue; c。 Glue quantity detection; d。 After the composite curing temperature, time control; After curing the composite strength between composite film; Amount of residual solvents; 3, high temperature cooking bags, bag making process check: a. Size of bag making, sealing side size; b。 Heat sealing side strength c. To bag and load capacity of water, such as sealing, place the bag samples between the pressure gauge, the lower pressure test, according to customer requirements for observing whether the bag burst and leakage. d。 Residual solvent volume 4, resistance to high temperature cooking check: after completion of bag making, will be sealed bag loading capacity of the contents and, in the ts - 25 c back pressure high-temperature cooking pot, set conditions and requirements of the customer test of high-temperature cooking; Appearance inspection: after cooking bag surface should be smooth, no wrinkles, foaming, deformation, no delamination, leakage phenomenon; If there are any kind of bad phenomenon is unqualified. Each procedure, the details of the perfect is the best guarantee of the quality of product. High temperature cooking bags, packaging cooking bags, cooking bags, high temperature cooking bags, please contact the hotline.
