Can't do this at 3 o 'clock, it is a good raw material can not do a good quality of high temperature cooking bags

High temperature cooking bags products is a complex process control requirements higher, if the improper control, has the good quality raw materials and produce good quality high temperature cooking bags products. And the larger is the cost of high temperature cooking bags, tend to appear quality problem, the loss is huge. Besides attention on raw materials, but also focus on what steps and details? To control the coating weight while adhesive coating weight is not the higher the better, but for high temperature cooking bags, products must have a certain amount of glue to ensure the resistance to cooking. General 121 ℃ cooking, glue quantity is 4. 0 ~ 5. 0g/㎡； 135 ℃ cooking, glue quantity is 4. 5 ~ 5. 5 g/㎡。 Pay attention to clean level of the compound 1, equipment, the relevant parts, such as glue system, all of the guide roller, pressure roller, bake, must be thoroughly clean, ensure the aluminum foil is not damaged, thin film is not wrinkled; 2, prevent dust impurities in composite film with a black spots impurities is a weak spot in high-temperature cooking ambient conditions, is likely to cause damage. Good control of temperature and humidity effects of compound roll temperature should be 80 ~ 90 ℃, to adopt the compound pressure, larger pressure is greater than zero. 4MPa。 Also because of the large amount of glue, should maintain good ventilation condition. Can be appropriately increase curing temperature and humidity control environment. High environmental humidity, on the one hand, adhesive performance; Commonly used high temperature cooking bags, on the other hand, base material of polyamide are easy to be affected.
