Description

Plastic composite soft packing bag with local scraping and coating layer

The technical field is as follows:

the utility model relates to a local has scraping knife coating layer plastics composite flexible packaging bag.

Background art:

in the market of national plastic composite soft packaging bags, plastic films of different materials are subjected to color printing and compounding to form a new plastic film, and then plastic composite soft packaging bags of various forms are produced, so that the plastic composite soft packaging bags are suitable for manufacturers with requirements of various industries on the plastic composite soft packaging bags, and reach a saturated state. At present, with the increasing demands of products in the market, the functional requirements of plastic composite flexible packaging bags are also increasing. At present, all manufacturers produce various common plastic composite flexible packaging bags without scraping coatings on the outer surface of the plastic composite flexible packaging bag body.

The utility model has the following contents:

the utility model aims at providing a local has scrapes knife coating layer plastic composite flexible packaging bag.

The above purpose is realized by the following technical scheme:

the utility model provides a local has and scrapes the compound flexible packaging bag of blade coating plastics, the compound flexible packaging bag surface local cover of plastics have and scrape the coating, scrape the coating be silver powder printing ink layer, thickness is 0.002~0.008mm, flexible packaging bag be trilateral envelope, self-supporting bag, zip fastener bag, self-supporting zip fastener bag, back envelope organ bag, four sides envelope, the three-dimensional envelope in side, octagon envelope, octagon zip fastener bag, dysmorphism bag or self-supporting suction nozzle bag, perhaps with the back envelope wrapping bag of roll membrane production on automatic packaging machine.

The local have scrape the compound flexible packaging bag of blade coating plastics, characterized by: the scraping and coating layer is positioned in the distance of 20-200mm from the upper opening or the lower opening of the flexible packaging bag.

Has the advantages that:

1. the utility model discloses scribble the outer part of the compound flexible packaging bag of plastics bag body and scrape the coating, it is different to the requirement of the compound flexible packaging function of plastics according to the customer, utilizes the part of external surface of bag to scrape the coating, characters or pattern below the cover coat to make things convenient for the trade company to the development of various commercial activities, prevent simultaneously that the consumer from under the condition of the activity that does not participate in the trade company and develop, fall to lead the activity reward, destroy the fairness.

2. The utility model discloses simple structure is fit for multiple packaging structure, and its distance apart from the boundary guarantees that should not wear and tear to the coating when stacking, can protect effectively in the transportation. The utility model discloses a coating coverage nature is strong, and the manual work can't normally take off, unless scraping, is particularly useful for sheltering from variable two-dimensional code, and the protection trade company utilizes the concealment before the activity of variable two-dimensional code organization.
