The success of general
food packaging production requires planning, designing, printing, compounding, curing, slitting, bag making, and finished products. Let's take a look at it:
1, plan
Is to develop a detailed plan before the production of food packaging bags, taking into account the characteristics of the food packaging bags produced, the size of the packaging bags, functional characteristics, pattern color text, etc.;
2, design
Design the packaging bag pattern, text, size, function, etc. according to the plan requirements and make the plate;
3, printing
The originals such as characters, patterns, photographs, etc. are subjected to plate making, ink application, pressurization, etc., so that the ink is transferred to the surface of the selected packaging material, and the original contents are copied in batches;
4, compound
The composite material is composited by dry compounding, so that the composite packaging material has the characteristics of a plurality of materials;
5, ripening
Put the composite packaging material into the curing chamber, and the curing agent is the main agent and the curing agent fully reflected under certain time and conditions to achieve the best composite effect;
6, cut
Separating and cutting the composite packaging materials according to actual needs;
7, bag making
The cut packaging material is made into a bag on the bag making machine;
8, quality inspection
Check the production bags for quality or other problems;
9, the finished product
Through strict inspection, quality qualified bags.
