In view of this, referring to fig. 1, fig. 1 is a schematic diagram illustrating steps of an integrated production method 1 for a self-heat-sealing film package according to the present invention.

The application provides an integrated production method 1 of film heat-seal packaging, which is applied to forming and folding of film composite packaging lining and packaging of products. It can be appreciated that the integrated production method of the film heat-seal package provided by the invention can be suitable for machine automated production processing.

It should be noted that, the film composite packaging liner generally includes at least the base plate 200 and the film 300, but the film composite packaging liner may be folded into a plurality of different packaging structures after being formed, so long as the final folded packaging structure of the film composite packaging liner can effectively package the product 400. In other words, the shape of the bottom plate 200 can be cut according to the requirement, the length of the film 300 can be adapted to the bottom plate and the product according to the requirement, the film composite package liner can be folded by different ways to form various package structures by folding the bottom plate 200 and the film 300, and the common points of the package structures can be used for compressing and fixing the product 400 through the cooperation of the bottom plate 200 and the film 300.

Referring to fig. 1 again, and referring to fig. 3 together, fig. 3 is a schematic structural diagram of a base plate 200 according to the present invention;

the invention provides an integrated production method 1 of a film package based on self-heat sealing, which comprises the following steps:

s1, providing a bottom plate 200, wherein the bottom plate 200 comprises a first wing plate 210, a bearing plate 220 and a second wing plate 230 which are sequentially connected, a first through hole 2101 is formed in the first wing plate 210, and a second through hole 2301 is formed in the second wing plate 230;

s2, placing the product 400 on the bearing plate 220;

s3, folding the first wing plate 210 and the second wing plate 230 towards the front of the bearing plate 220 respectively, so that the first wing plate 210 and the second wing plate 230 stand on two sides of the bearing plate 220 respectively;

s4, providing a film roll 11, pulling one end of the film 300 on the film roll 11 to the first wing plate 210, enabling the film 300 to be positioned on two sides of the first wing plate 210 away from each other and cover the first through hole 2101, heating and pressing the film 300 positioned at the first through hole 2101, and self-heat-sealing the film 300 at the first through hole 2101 to enable the film 300 to be connected with the first wing plate 210;

s5, continuously pulling the film 300 on the film roll 11 to the second wing plate 230, so that the film 300 is positioned at two sides of the second wing plate 230, which are away from each other, and covers the second through hole 2301, heating and pressing the film 300 positioned at the second through hole 2301, and self-heat-sealing the film 300 at the second through hole 2301 to connect the film 300 to the second wing plate 230;

S6, cutting the film 300 from the film roll 11;

s7, folding the first wing plate 210 and the second wing plate 230 towards the back of the bottom plate 200, so that the film 300 stretches and the product 400 is pressed on the bearing plate 220.

By the arrangement, the forming, folding and packaging of the film composite packaging lining and the fixing of the product 400 can be completed through one production line, so that the occupied area of the production line is effectively reduced, and the whole flow and the production time are saved; in addition, since the product 400 can be placed on the base plate 200 in advance in the process of connecting the film 300 with the base plate 200, the storage cost can be greatly saved; in addition, the integrated production method 1 provided by the invention can enable the two sides of the film 300 to form annular and annular connection structures with the first wing plate 210 and the second wing plate 230 respectively through the self-heat sealing mode of the film 300, so that the connection reliability between the film 300 and the bottom plate 200 is effectively improved; the risk of the connection between film 300 and base 200 becoming detached due to the tensile force created by the tensioning of film 300 as base 200 folds over packaged product 400 is reduced.

In other words, in the traditional film composite packaging lining, two ends of the film are generally adhered to two ends of the bottom plate in a direct flat adhesion mode, when the bottom plate is folded to form a packaged product, the film can be tensioned and stretched in the folding process and the height of the product, the two ends of the film are easy to be degummed with the bottom plate under the action of tension, and when the film is manually packaged, a worker can relatively control folding force or pinch two ends of the film to adhere part in a mode of pinching two hands, so that the risk of film degumping is reduced; but on the production line, the machine is difficult to control the processing force flexibly like the manual work, so in the prior art, after the film composite package lining is generally molded, the film composite package lining needs to be placed in a factory to stand, and after the film and the bottom plate colloid are cured and connected relatively firmly, the film and the bottom plate colloid are taken out again, the product is placed in the lining, and the package is completed through folding. This process needs to pass through two production lines, and two production lines switch in-process and still need get into the warehouse and store, and overall process is loaded down with trivial details, and is consuming time for a long time, need occupy great factory storehouse and store, and manufacturing cost and storage cost are all higher.

The mode of the connection structure between the production flow and the bottom plate 200 and the film 300 is changed, so that the forming, folding and packaging of the film composite packaging lining and the fixing of the product 400 can be completed through one production line, the occupied area of production equipment is effectively reduced, the whole flow and the time consumption of production are saved, meanwhile, a large amount of storage space can be prevented from being occupied, and the production cost is effectively reduced.

Specifically, in the present application, the product 400 is placed on the carrier plate 220 of the base plate 200 before the film 300 is connected with the base plate 200, and the process of forming the liner of the film composite package, folding the film 300 into a package structure after being connected with the base plate 200, and packaging the product 400 can be cross-conducted without being produced in two production lines. In addition, the through holes are formed in the first wing plate 210 and the second wing plate 230 of the bottom plate 200, the first wing plate 210 and the second wing plate 230 are folded and laterally stand on two sides of the bearing plate 220, so that films 300 can be conveniently coated on two sides of the through holes, the films 300 on two sides of the through holes are pressed in a heating and pressing mode to be self-heat-sealed, a cross-buckled connection structure can be formed between the self-heat-sealed films 300 and the first wing plate 210 of the bottom plate 200 through the first through holes 2101, the connection strength between two ends of the films 300 and the bottom plate 200 is greatly improved, and the situation that the films 300 are separated from the bottom plate 200 when the films 300 and the bottom plate 200 are folded to package the product 400 is effectively reduced or avoided.

It should be noted that "side standing" of the first wing plate 210 and the second wing plate 230 standing on two sides of the carrier plate 220 respectively represents that an included angle between the first wing plate 210 and the second wing plate 230 and the carrier plate 220 may be 90 degrees or may be greater than or less than 90 degrees when the first wing plate 210 and the second wing plate 230 are turned and standing. In this embodiment, the side stand angle is preferably 90 degrees.
