Description
Technical Field
The utility model relates to the production and field of packaging films, in particular to a five-layer co-extrusion FFS heavy packaging film.
Background
FFS is an integrated abbreviation of bag making (Form), filling (Fill) and sealing (Seal), is an advanced automatic packaging system, and is characterized by fast packaging, one-step forming, and good sealing moisture resistance and printing performance. The repackaging film generally adopts a three-layer co-extruded film, and when the conventional three-layer co-extruded repackaging film is used, patterns or characters are printed on the surface of the repackaging film, and when the repackaging film is recycled, the color of the recycled and regenerated film is not uniformly distributed due to the printed patterns or characters. The requirement of customers on the appearance of the heavy packaging film is very high, and the requirements of customers cannot be met when the heavy packaging film with the printing ink is recycled.
SUMMERY OF THE UTILITY MODEL
The utility model aims to design a five-layer co-extrusion FFS heavy packaging film, so that an outer layer film is peeled off, and the influence of printing ink on the heavy packaging film during recovery and regeneration is avoided.
In order to achieve the purpose, the utility model provides the following technical scheme: a five-layer co-extrusion FFS heavy packaging film sequentially comprises a first layer film, a second layer film and a third layer film from inside to outside; a transition film is arranged on the outer surface of the third film; a stripping film for printing is arranged on the outer surface of the transition film; the first layer film, the second layer film, the third layer film, the transition film and the stripping film are formed by co-extrusion; the thickness of the release film is smaller than the thickness of the other four films.
Further, a plurality of micropores are distributed on the surface of the transition membrane. The micropores on the transition film reduce the contact area with the stripping film, thereby facilitating the stripping of the stripping film and the transition film.
Further, micropores on the surface of the transition membrane are uniformly distributed. The uniformly distributed micropores can facilitate that the force required for separation is uniform in the process of separating the whole stripping film, and reduce the phenomenon that the stripping film is broken in the process of separating the stripping film.
Further, the thickness of the release film is 5 to 15 micrometers. Within the thickness range, the printing ink has certain strength and can meet the printing requirement.
Further, the total thickness of the first layer of film, the second layer of film, the third layer of film, the transition film and the release film is 120 to 180 micrometers. Meanwhile, the thickness of the heavy packaging film is 120-180 micrometers, so that the requirement of the heavy packaging film on the packaging strength is met, and the production cost can be reduced.
Further, the thickness ratio of the first layer of film, the second layer of film and the third layer of film in sequence is 1:2: 1. The film layer with the thickness proportion reduces the requirement on film blowing equipment, effectively lightens the working load of the extruder and prolongs the service life of the equipment.
Further, a metallocene resin is added into the release film. The heat sealability of the release film can be increased.
Further, the types of raw materials of the first layer film, the second layer film, the third layer film and the release film are the same. The use of raw material types is reduced, and the influence of other raw materials can be reduced during recovery.
Compared with the prior art, the utility model has the beneficial effects that: the printing work is realized on the stripping film through the arranged stripping film, and the arrangement of the transition film can help the stripping film to be separated from the transition film. When the stripping film is recovered, the stripping film is separated from other four-layer films, so that the four-layer films are not influenced by printing ink. The recycled packaging film has uniform color and can meet the requirements of customers. And the stripping film affected by the ink can be used for packaging products with lower appearance requirements due to uneven color after being recycled and regenerated, so that resources are fully utilized.

Example (b):
a five-layer co-extrusion FFS heavy packaging film sequentially comprises a first layer film 1, a second layer film 2 and a third layer film 3 from inside to outside; the outer surface of the third film 3 is provided with a transition film 4; the outer surface of the transition film 4 is provided with a stripping film for printing; the first layer film 1, the second layer film 2, the third layer film 3, the transition film 4 and the stripping film are formed by co-extrusion; the thickness of the release film is smaller than the thickness of the other four films.
It should be noted that the co-extrusion here is to mix the first layer film, the second layer film, the third layer film, the transition film and the peeling film in their corresponding single screw extruders, and to convey the packaging film raw material mixed into fluid state into the five-layer extruders for fusion extrusion.
The surface of the transition membrane 4 is distributed with a plurality of micropores. The micropores on the transition film 4 reduce the contact area with the stripping film, so as to facilitate the stripping of the stripping film from the transition film 4. The micropores on the transition membrane are formed by adding the nano calcium carbonate master batch when the transition membrane is mixed in a single screw extruder.
The micropores on the surface of the transition membrane 4 are uniformly distributed. The uniformly distributed micropores can facilitate that the force required for separation is uniform in the process of separating the whole stripping film, and reduce the phenomenon that the stripping film is broken in the process of separating the stripping film.
The thickness of the release film is 5 to 15 micrometers. Within the thickness range, the printing ink has certain strength and can meet the printing requirement.
The total thickness of the first layer film 1, the second layer film 2, the third layer film 3, the transition film 4 and the release film is 120 to 180 micrometers. Meanwhile, the thickness of the heavy packaging film is 120-180 micrometers, so that the requirement of the heavy packaging film on the packaging strength is met, and the production cost can be reduced.
The thickness ratio of the first layer film 1, the second layer film 2, and the third layer film 3 in this order is 1:2: 1. The film layer with the thickness proportion reduces the requirement on film blowing equipment, effectively lightens the working load of the extruder and prolongs the service life of the equipment.
Metallocene resin is added into the stripping film. The heat sealability of the release film can be increased.
The types of the raw materials of the first layer film 1, the second layer film 2, the third layer film 3, and the release film 5 are the same. The use of raw material types is reduced, and the influence of other raw materials can be reduced during recovery.
The working principle of the embodiment is as follows:
when the five-layer co-extruded FFS heavy packaging film is recycled, the stripping film 5 is placed into a corresponding stripping device, the stripping film 5 is separated in the stripping device, the first layer film 1, the second layer film 2, the third layer film 3 and the transition film 4 enter corresponding positions to be recycled, and the stripping film 5 also enters corresponding positions to be recycled. The first layer film 1, the second layer film 2, the third layer film 3 and the transition film 4 are recycled and regenerated without the influence of printing ink, so that the regenerated colors are not changed, and the requirements of customers on the appearance color of the repackaging film can be met. The stripping film 5 with printing ink can have certain color after regeneration, can be used for packaging articles with colors not in the appearance of the package, and fully utilizes resources.
The utility model has the beneficial effects that: the printing work is realized on the stripping film through the arranged stripping film, and the arrangement of the transition film can help the stripping film to be separated from the transition film. When the stripping film is recovered, the stripping film is separated from other four-layer films, so that the four-layer films are not influenced by printing ink. The recycled packaging film has uniform color and can meet the requirements of customers. And the stripping film affected by the ink can be used for packaging products with lower appearance requirements due to uneven color after being recycled and regenerated, so that resources are fully utilized.
