What are the steps in the production process of food packaging bags?
A variety of packaging bags are filled with our daily life, and the reason is that different foods should be packed in specific bags. So how do different kinds of bags come from wholesale packaging supplies?
The production of a bag by wholesale packaging can be roughly divided into 6 steps: design, plate making, layout printing, compounding, bag curing, slitting, and bag making. Let’s take a look at the specifics below.
1. Package Design: This is to design the layout of the food vacuum bag according to the requirements of the food company. The design layout of a good food packaging bag has a good effect on improving the sales volume of the product.
2. Plate making: It is based on the confirmed draft of the food packaging bag design to produce the copper plate required on the food packaging printing machine. This version is a cylinder, and it is a complete set that is not a single one. The exact size of the version should be determined based on the packaging design of the previous step by wholesale packaging supplies.
3, layout printing: the specific content of the work in the food packaging and printing machine, according to the first layer of material confirmed by the food company (the confirmation of the material can refer to the basis of the vacuum bag) for printing, the effect diagram and the design artwork printed out Too much difference.
4, compound: the so-called compound is the two total materials are bonded together, the ink surface is stuck in the middle of the two materials, such as pa (nylon) / pe (enhanced), which nylon is the first layer of material that is printed material , pe (enhancement) is the second layer of material that is composite material, in some cases there will be third and fourth layers of material. The third layer is needed to make an ordinary aluminum foil bag (opp film/al foil/pe enhancement). Note: It is usually necessary to examine the previously printed material one step prior to compounding, eliminating poorly printed materials.
5, food packaging bags for curing.
6, food packaging bags for cutting or bagging: Slicing is for automatic packaging film (pillow packaging film), bag making is made with a bag making machine a packaging bag.
