Example Embodiment

[0041] Example 1:

[0042] See Figure 1-Figure 6 The present invention includes the inner layer forming process, the outer layer color printing process, the composite process, the shearing process, the bag opening forming process, the bottom sealing process and the gluing process. The inner layer forming process includes the film forming step, the cutting step and the weaving step, The bag opening shaping process includes a bag opening forming step and an indentation forming step.

[0043] In the present invention, the inner layer forming process uses plastic particles as raw materials. In this embodiment, the main component of the plastic particles is polypropylene, and the polypropylene plastic particles are the prior art. In this embodiment, polypropylene plastic particles are first made into a film at 240°C. The film made at this temperature has better performance. The film making step in the present invention is the same or similar to the prior art. The film forming temperat...

Example Embodiment

[0055] Example 2:

[0056] See Figure 7-12The processes in this embodiment include the inner layer forming process, the outer layer color printing process, the composite process, the edge drawing process, the shearing process, the bag opening forming process, the bottom sealing process and the gluing process, and the inner layer forming process includes the film forming step , The cutting step and the weaving step, the bag opening shaping step includes the bag opening forming step and the indentation forming step.

[0057] The edge extraction process in this embodiment is located between the composite process and the shearing process. The difference between this embodiment and the first embodiment is that this embodiment has one more edge extraction process than that of the first embodiment. The steps are the same as those in Example 1. The inner layer forming process, outer layer color printing process, and composite process in this embodiment are all the same as those in embodim...

Abstract

The invention relates to a preparation method of woven compound mail package bags, belonging to the preparation process of mail package bags. Presently, in the absence of preparation process of mail package bags, the existing mail package bags are mostly simple homemade packages. The preparation method in turn comprises processes of inner layer molding, compounding, cutting and bottom sealing; wherein, the inner layer molding adopts plastic particles as raw materials, the inner layer molding process in turn comprises processes of film preparing, shredding and weaving; the invention is characterized in that: the preparation method further comprises processes of outer layer color printing, bag mouth molding and rubberizing; wherein, the outer layer color printing process is carried out on the paper-imitating pearlescent film, the outer layer color printing process is prior to the compounding process, the bag mouth molding is between the cutting process and the bottom sealing process, the rubberizing process is behind the bottom sealing process. The preparation method has simple preparation process, the prepared package bag has firm structure, strong seal and convenient use, and relative mail information can be written directly on the bag.

Description

technical field [0001] The invention relates to a manufacturing method of mail packing bags, in particular to a manufacturing method of mail woven composite packing bags, which belongs to the manufacturing process of mail packing bags. Mail woven composite packaging bags are mainly used for packaging postal items, such as packaging bags that can be used as parcels, envelopes for letters, etc., and belong to postal packaging bags. Background technique [0002] At present, there are many kinds of packaging bags used for mailing. For example, the packaging bags used for mailing letters are usually paper envelopes. These paper envelopes are usually suitable for mailing letters with fewer pages, and it is necessary to ensure that the letters Because these paper envelopes are usually not waterproof, once the letter encounters water, the letter inside the envelope will be damaged, which brings certain difficulties to the delivery work. And these paper envelopes are easy to break d...
