Embodiment

[0024] The production process of leisure snack packaging bags includes the following steps:

[0025] 1) Material preparation: Prepare the required materials and place them on the corresponding device;

[0026] 2) Raw material hole detection: use the hole detection unit to detect the holes on the raw material film, and mark the holes;

[0027] 3) Printing and plate making: use the correction unit to limit and correct the position of the film, and then send the film into the printing machine for printing;

[0028] 4) Composite curing: the curing temperature is 50-70°C;

[0029] 5) Fixing the sealing strip: the sealing strip is hot-pressed and fixed to the side of the film that has no printed pattern through the sealing strip fixing unit;

[0030] 6) Film cooling: cooling the film with the sealing strip fixed, the cooling temperature is 5-15°C;

[0031] 7) Slitting bag making: After slitting, select the marked semi-finished packaging bags, and then make bags.

Abstract

The invention relates to the technical field of food packaging bag production processes, and discloses a production process for a snack packaging bag. The production process comprises the following steps: (1) preparing materials; (2) printing and plate-making, wherein a deviation correcting unit is utilized to limit and correct the position of a film, and then, the film is fed into a printer to print; (3) compounding and curing; (4) fixing a sealing strip, wherein the sealing strip is fixed onto one surface, without a printed pattern, of the film through a sealing strip fixing unit; and (5) slitting and making the bag. According to the scheme adopted by the invention, the production process solves the problem that printing dislocation is caused as a film is not flat and tilts in a film printing process.

Description

technical field [0001] The invention relates to the technical field of production technology of food packaging bags, in particular to a production technology of leisure snack packaging bags. Background technique [0002] At present, the production process of food packaging bags generally includes: material preparation, printing plate making, composite curing and slitting bag making. Most casual snacks, such as all kinds of nuts, potato chips, biscuits, etc., generally do not eat a whole bag at one time. When these snacks are packed in commonly used packaging bags, there is no part that can be eaten at one time, and the taste is easily affected by moisture. , and prone to corruption. [0003] In the prior art, a sealing strip that is fixed and recycled in the packaging bag is often used, so that the packaging bag can be sealed to prevent the snacks in the packaging bag from being damp and deteriorating. In the existing production process, the film is prone to problems such ...
