Embodiment 1

[0056] This embodiment provides a packaging film for frozen drinks, the packaging film is a two-layer composite film structure, and the two-layer composite film is respectively a printing protection layer and a heat-sealing layer; wherein, the printing protection layer is located at the most The outer layer is made of conventional materials such as biaxially oriented polypropylene film BOPP film. The printing protective layer has good printing adaptability, good dimensional stability, excellent gloss and transparency, and has protective functions; the thermal The sealing layer is on the opposite side of the printing protective layer. The heat-sealing layer is made of PP and color masterbatch materials through a specific weight ratio. The specific composition ratio (percentage of the total weight of the heat-sealing layer material) is : Masterbatch accounts for 8%, PP accounts for 92%.

[0057] Preparation:

[0058] (1) Preparation of PP+ masterbatch mixture:

[0059] Put 80 ...

Embodiment 2

[0062] A two-layer composite film structure packaging film for frozen drinks, the packaging film includes a print protection layer and a heat-sealing layer; wherein, the print protection layer is made of conventional materials such as biaxially oriented polypropylene film BOPP film, The printing protective layer has the advantages of good printing adaptability, good dimensional stability, excellent gloss and transparency, and protective function; the heat-sealing layer is on the other side of the printing protective layer, made of PP and color The masterbatch and masterbatch materials are made through a specific weight ratio, and the specific composition ratio (percentage of the total weight of the heat-sealing layer material) is as follows: color masterbatch accounts for 9%, and PP accounts for 91%.

[0063] Preparation:

[0064] (1) Preparation of PP+ masterbatch mixture:

[0065] Put 90 kg of color masterbatch and 910 kg of PP particles in a container, and stir and mix for...

Embodiment 3

[0068] A packaging film with a composite film structure including a printed protective layer and a heat-sealing layer, the packaging film is mainly used for the outer packaging of frozen drinks; the printed protective layer is made of biaxially oriented polypropylene film BOPP film, so the printed The protective layer has good printing adaptability, good dimensional stability, excellent gloss and transparency, and protective function; the heat-sealing layer is on the outside of the printing protective layer, and is made of two materials including PP and color masterbatch after a specific weight ratio Manufactured, its specific composition ratio (accounting for the percentage of the total weight of the heat-sealing layer material) is: color masterbatch accounts for 10%, PP accounts for 90%.

[0069] Preparation:

[0070] (1) Preparation of PP+ masterbatch mixture:

[0071] Put 100 kg of masterbatch and 900 kg of PP particles in a container, stir and mix for about half an hour ...

Abstract

The invention provides a packing film for frozen beverages. The packing film comprises a composite film of a printing protective layer and a thermal sealing layer, the materials of the thermal sealing layer comprise PP and color master batch, wherein the color master batch accounts for 8 to 10 percent of total weight of the materials for the thermal sealing layer, and the PP accounts for 90 to 92 percent of total weight of the material for the thermal sealing layer. The invention also provides a method for preparing the packing film. The packing film as a product can reach the printing level and the using effect of the prior pearly-luster OPP, is superior to the effect of the pearly-luster OPP, has low cost, and more accords with the environmental protection requirement.

Description

technical field [0001] The invention provides a packaging material, in particular to a packaging material in the field of food, especially a packaging film for frozen drinks. Background technique [0002] At the present stage, in the field of food packaging, specifically cold drinks, the commonly used packaging film is a composite film with a two-layer structure, that is, the outermost printing protective layer, which requires good printing adaptability, good size Stability, gloss and transparency are excellent, and have certain protective functions. Generally, BOPP film is used, that is to say, biaxially oriented polypropylene (BOPP) film is used as the printing protective layer, and the other side of the printing protective layer is a heat-sealing layer. , is also the inner layer relative to the outer layer. According to different packaging materials, it mainly plays the role of moisture barrier, oxygen barrier, and light barrier. It is chemically inert and has a certain ...
