Example Embodiment

[0025] Example 1

[0026] The heat-insulating high-stiffness food packaging film includes the following composite layers, and the following composite layers are composited into a high-stiffness heat-insulating food packaging film through an up-and-down double-roll extrusion method. The control nip pressure of the pressing compound zone is 100-120kN / m; the temperature of the hot air drying curve in the latter section is 60-80℃, and the moisture in the drying zone is controlled to be 9-15% relative to the total mass of the packaging film. Each layer of the compound layer is , See figure 1 :

[0027] (1) The first composite layer 1, choose corona pretreatment, a PET film with a thickness of 12-18μm, the bottom of the PET film is printed with patterns and sizing, the sizing amount is 8-10g / m 2 , The curing capacity is 3-5g / m 2 ;

[0028] (2) The second layer of composite layer 2, choose food-grade packaging paper, the basis weight of food-grade packaging paper is 40-60g / m 2 , Longit...

Abstract

The invention discloses a food packaging film with heat insulation property and high stiffness. The Food packaging film with the heat insulation property and high stiffness comprises composite layers, wherein the composite layers are composited and processed into the food packaging film with the heat insulation property and high stiffness in an upper-lower double-roller extrusion manner, and the control pressure zone pressure of an upper-lower double-roller extrusion composite zone is 100-120 kN/m; the temperature of a back-section hot air drying curve is 60-80 DEG C, and moisture of a drying zone is controlled to be 9%-15% of the total mass of the packaging film. The food packaging film has the advantages as follows: the stiffness performance is excellent, the heat and light insulation performance is good, and the food packaging film is quite suitable for packaging food such as lollipops and the like.

Description

technical field [0001] The invention belongs to the field of packaging films, in particular to a food packaging film with heat insulation and high stiffness. 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 object of the present invention is to overcome the disadvantages and deficiencies of the prior art, and provide a heat-insulating high-stiffness food packaging film suitable for food packaging such as lollipops, convenient and exquisite in printing, and beautiful in packaging. [0004] Anothe...
