Inspection of high-temperature cooking bag making process

When we produce high-temperature cooking bags, we need to check many places to ensure the quality of the bags. So what needs to be tested in the process of high-temperature cooking bag making? Let experts introduce it to us.

Our technical experts said that in order to ensure the product quality is qualified, we need to check the following points when producing high-temperature cooking bags:

1. Bag size and edge size specifications (according to customer requirements).

2. The heat sealing strength is measured by cutting a 15mm wide test piece from the edge seal of the bag with a steel ruler and fixing it on the upper and lower clamps of the LDX-200 universal material testing machine.

3. Fill the bag with water of equal capacity and seal it, place the bag sample between the upper and lower plates of the pressure gauge, and conduct pressure test according to the conditions (pressure, time) required by the customer to observe whether the bag is broken and leaking.

4. For residual solvent detection, cut 0.2m2 of sample, quickly cut the sample into 10mm30mm pieces, put it into a clean conical flask preheated at 80 ℃ and about 500ml, seal it with a silica gel stopper, put it into an 80 ℃ thermostat for 30min, and then use a 5ml syringe to take 1ml of gas sample from the bottle and inject it into the 2061C gas chromatograph for determination, and the result is qualified with ≤ 10mg/m2.

The above is the introduction of the inspection items in the process of making high-temperature cooking bags. If you are interested in the high-temperature cooking bags produced by our factory, please contact Jiangsu Gengda Packaging Co., Ltd. by telephone. After Z, I wish you a happy life.
