Problems solved by technology

[0002] At present, all lollipop packaging is made by wrapping the bottom of the package with twists and hot irons, which is unhygienic, poorly sealed and not heat-insulated, and damages the packaging film, which does not reflect the overall appearance of the printed shape. For reasons such as easy sugar sticking, poor heat insulation and sealing, short shelf life, etc., the packaging film often sticks to sugar and it is difficult to open and eat, which is not satisfactory.

Embodiment 1

[0027] The high-stiffness heat-insulating food packaging film includes the following composite layers, and the following composite layers are processed into a high-stiffness heat-insulating food packaging film through upper and lower double-roll extrusion, wherein the upper and lower double-roll extrusion The control nip pressure in the composite zone is 100-120kN / m; the temperature of the hot air drying curve in the rear section is 60-80°C, and the moisture in the drying zone is controlled to be 9-15% relative to the total mass of the packaging film. The composite layers of each layer are, see figure 1 :

[0028] (1) The first layer of composite layer 1, choose corona pretreatment, the thickness is 12-18μm PET film, the bottom surface of the PET film is printed with patterns and sizing, the sizing amount is 8-10g / m 2 , the curing amount is 3-5g / m 2 ;

[0029] (2) The second layer of composite layer 2, choose food grade wrapping paper, food grade wrapping paper quantitativ...

Abstract

The invention discloses a processing method for a high-stiffness heat-insulation foodstuff packaging film and the product. The high-stiffness heat-insulation foodstuff packaging film comprises following composite layers, and the composite layers are combined in an extrusion manner by employing an upper roll and a lower roll for processing the high-stiffness heat-insulation foodstuff packaging film, the pressure of a control pressure zone of an upper and lower roll extrusion combination zone is 100-120 kN / m, the rear-segment hot-air drying curve temperature is 60-80 DEG C, and the water content when the film is discharged from a drying zone is 9-15% by mass of the packaging film. The advantages comprise that the packaging film is excellent in stiffness and good in thermal-insulation light-insulation properties, and is extremely suitable for packaging of lollipops and other foodstuff.

Description

technical field [0001] The invention belongs to the field of packaging films, and specifically refers to a high stiffness and heat-insulating food packaging film processing method and a product thereof. Background technique [0002] At present, all lollipop packaging is made by wrapping the bottom of the package with twists and hot irons, which is unhygienic, poorly sealed and not heat-insulated, and damages the packaging film, which does not reflect the overall appearance of the printed shape. For reasons such as easy sugar sticking, poor heat insulation and sealing, and short shelf life, the packaging film often sticks to sugar and is difficult to open and eat, which is not satisfactory. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a food packaging film processing method suitable for food packaging such as lollipops, which is convenient and exquisite in printing, bea...
