Technical Field

The invention relates to the technical field of packaging, in particular to a packaging method.

Background

The current common article package is generally packaged by a corrugated paper box matched with an internal buffer packaging structure. However, the corrugated paper box has a complex structure and complicated packaging and forming steps in a packaging form by matching with an internal buffer belt.

Disclosure of Invention

Therefore, a packaging method with simple steps and convenient packaging needs to be provided for solving the technical problems.

In order to achieve the purpose, the invention adopts the following technical scheme:

a method of packaging, comprising the steps of:

providing a bottom plate and a film;

applying a pressure sensitive adhesive and/or adhesive to the base plate or the film;

compounding the film on the bottom plate to form a sealing area for accommodating a product;

and folding the bottom plate to stretch the film.

Folding the two ends of the bottom plate downwards along the first pressing line to stretch the film; and/or folding the two sides of the bottom plate upwards or downwards along the second pressing line to stretch the film.

In the application, the film is compounded on the bottom plate, and the bottom plate stretching film is folded, so that the product is sealed and fixed, and the packaging steps are simple, convenient and low in cost.

In one embodiment, the bottom plate is manufactured by the following steps:

providing a substrate having a front side and a bottom side;

coating a waterproof layer with different polarity from the pressure-sensitive adhesive on the bottom surface of the base material;

die-cutting two groups of first press lines arranged longitudinally and two groups of second press lines arranged transversely on the front surface of the base material, wherein the first press lines and the second press lines are arranged in a crossed manner and enclose an accommodating area; and

two groups of folding lines parallel to the second pressing line are die-cut on the front surface of the base material, and the two groups of transversely arranged second pressing lines are positioned between the two groups of folding lines.

It will be appreciated that the water/moisture resistant treatment of the bottom surface of the substrate further keeps the product in a hermetically sealed environment, preventing moisture exchange.

In one embodiment, in the step of folding over the base sheet to stretch the film:

folding the two ends of the bottom plate downwards along the first pressing line to stretch the film; and/or folding the two sides of the bottom plate upwards or downwards along the second pressing line to stretch the film.

In one embodiment, after the step of die-cutting two sets of folding lines parallel to the second pressing lines on the front surface of the base material, the step of manufacturing the base plate further comprises the following steps:

coating at least two pressure-sensitive adhesives between the two groups of first press lines; and

and folding two ends of the base material along the folding line from outside to inside to form side plates, and enabling the bottom surface of the base material to be positioned on the front surface so that the pressure-sensitive adhesive is shielded by the side plates.

In one embodiment, the width of the pressure sensitive adhesive is greater than or equal to 15 mm.

It can be understood that the width of the pressure sensitive adhesive is set to be greater than or equal to 15mm, so that the connection area between the film and the bottom plate can be ensured, and the connection strength between the film and the bottom plate can be improved.

In one embodiment, after the step of folding the two ends of the base material along the folding line from outside to inside and positioning the bottom surface of the base material on the front surface to shield the pressure-sensitive adhesive, the packaging method further comprises the following steps:

and attaching the film to the side plate.

It can be understood that the film is attached to the side plates, namely the film is in contact with the waterproof layer, so that the film bottom plate can be prevented from being in contact with each other in the transportation process, and the problem that the film and the bottom plate are adhered to each other by self under the pressure generated by stacking, extruding and the like can be avoided.

In one embodiment, after the step of attaching the film to the side panel, the packaging method further comprises the steps of:

and lifting the film from the side plate, and turning the side plate from inside to outside by a preset angle so as to place the product into the sealing area from the gap between the film and the bottom plate.

In one embodiment, after the step of cutting two sets of fold lines parallel to the second score line on the front side of the substrate, the method of packaging further comprises the steps of:

coating at least two pressure-sensitive adhesives on two sides of the film;

folding two sides of the base material from outside to inside along the folding line to form side plates, and enabling the bottom surface of the base material to be positioned on the front surface; and

and respectively attaching the two sides of the film to the side plates on the two sides of the base material.

In one embodiment, after the step of folding the two sides of the base material along the folding line from outside to inside to form the side panels and making the bottom surface of the base material be located on the front surface, the packaging method further comprises the following steps:

turning over two sides of the side plate from inside to outside respectively to form sub side plates parallel to the front surface;

and respectively attaching the two sides of the film to the sub-side plates.

In one embodiment, after the step of laminating the film to the base sheet and forming the sealed region with the product therein, the packaging method further comprises the steps of:

and heating the base plate with the film.

It will be appreciated that the base of the film is heat treated to increase the adhesion of the adhesive between the film and the base and to improve the strength of the bond between the two.

In one embodiment, after the step of applying a pressure sensitive adhesive and/or adhesive on the base sheet or the film, the packaging method further comprises the steps of:

and carrying out corona treatment on the film.

It will be appreciated that corona treatment of the film increases the adhesion between the adhesive and the film and improves the strength of the bond between the two.

Compared with the prior art, the packaging method has the advantages that the film is compounded on the bottom plate, the bottom plate is folded and stretched, so that the product is sealed and fixed, the packaging steps are simple and convenient, and the cost is low.
