Embodiment Construction

[0011] Below in conjunction with specific embodiment the present invention is described in further detail:

[0012] The present invention is realized through the following steps:

[0013] Detect the shrinkage stress value of various films under low temperature conditions;

[0014] Test the 90-degree peeling and 180-degree peeling force values ​​of various food-grade low-temperature-resistant laminating glues in a low-temperature environment;

[0015] The peeling force of the glue must be greater than the shrinkage stress of the film;

[0016] Determine the proper ratio of film and glue.

[0017] In the present invention, 90 degrees refers to the force perpendicular to the glue surface; 180 degrees refers to the force parallel to the glue surface.

Abstract

The invention relates to a control method for laminated low-temperature-resistant films of a packaging box. The control method is realized by the steps of: detecting the shrinkage stress value of various films in a low-temperature condition; detecting the 90-degree peel strength and 180-degree peel strength of various food-grade low-temperature-resistant laminating glues in a low-temperature environment after the glue is applied; ensuring that the peel strength of the glue is greater than the shrinkage stress value of the films; and determining a proper proportion between the films and the glue. The control method for the laminated low-temperature-resistant films of the packaging box provided by the invention has the beneficial effect that the temperature endurance of the packaging box can be figured out in a design phase according to the characteristics of the materials in a low-temperature state, thus reducing the time, cost and efforts of design and development.

Description

technical field [0001] The invention relates to a packaging box, in particular to a method for controlling the low-temperature resistant coating of the packaging box. Background technique [0002] Many of the current packaging boxes use film-coating technology, but at low temperatures, film-coated products are often prone to instability problems. [0003] How to detect the adhesion of the film on the surface of the packaging box before it is produced is what technicians need to consider. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a method for controlling the low-temperature resistant coating of a packaging box, aiming at solving the above-mentioned problems. [0005] In order to solve the problems of the technologies described above, the present invention is achieved through the following steps: [0006] Detect the shrinkage stress value of various films under low temperature conditions; [0007] Test the...
