Problems solved by technology

The sales volume of washing products has also increased significantly. The existing washing powder packaging materials are 12PET / 100PE from the outside to the inside. The initial heat sealing temperature of the above-mentioned thin materials is 120-130°C, and the relative energy consumption in the packaging process is relatively high. , at the same time, the total thickness of the material reaches 112um, which is a serious waste of social resources

[0059] Outer layer: RC1314 (co-PP) is a copolymerized PP, which has good compatibility with PE in terms of melting point and melting index. SP1520 is 6C MLLDPE, because metallocene polyethylene and PP materials have good blending compatibility, t...

Embodiment 2

[0070] Except 2) preparation process of polypropylene and polyethylene blending and co-extrusion thin material layer: middle,

[0071] Corona layer: 65KgRC1314 (co-PP); 25KgSP1520; 7Kg150BW; 0.5Kg100991-k

[0072] Middle layer: 25KgF920A; 30Kg1018FA; 30Kg2426H; 15Kg white female F501; 0.3Kg100991-k;

[0073] Heat seal layer: 25Kg Yanshan 100AC; 30g1002KW; 30Kg5100G; 1.5KgSE07PE; 0.8KgAB-20LD; 0.3Kg100991-k;

[0074] 3) In the extrusion compounding process,

[0075] The weight ratio of LDPE 1C7A to SP1071C is 1:3

[0076] Outside, all the other are identical with embodiment 1.

Embodiment 3

[0078] Except 2) preparation process of polypropylene and polyethylene blending and co-extrusion thin material layer: middle,

[0079] Corona layer: 70KgRC1314 (co-PP); 30KgSP1520; 30Kg150BW; 0.8Kg100991-k

[0080] Middle layer: 25KgF920A; 35Kg1018FA; 38Kg2426H; 22Kg white female F501; 0.3Kg100991-k;

[0081] Heat seal layer: 30Kg Yanshan 100AC; 25Kg1002KW; 30Kg5100G; 2.0KgSE07PE; 1.5KgAB-20LD; 0.4Kg100991-k;

[0082] 3) In the extrusion compounding process,

[0083] The weight ratio of LDPE 1C7A to SP1071C is 1:3.5

[0084] Outside, all the other are identical with embodiment 1.

[0085] The technical index of embodiment 1-3 is as follows:

Abstract

The invention discloses a thinning lightweight packaging material and a preparation method thereof. The packaging material comprises a PET (Polyethylene Terephthalate) polyester film layer, a functional polyethylene film layer and a polypropylene and polyethylene co-extruded and blended film layer from outside to inside, respectively. Compared with the prior art, the invention has the following advantages of: (1) clear and bright appearance, good effect on shelves and capability of improving product grades; (2) low temperature, short heat-sealing time, high sealing strength and capability of reducing packaging cost; (3) small friction coefficient, applicability for modern rapid automatic packaging equipment, fast packaging speed and high efficiency; (4) high performance and good weather resistance; (5) low-temperature heat-sealing formula; the heat-sealing temperature of the ordinary packaging material for washing powder is 120-130 DEG C, and the heat-sealing temperature of the thinning lightweight packaging material disclosed by the invention can be controlled at 100-110 DEG C; and (6) on the premise of improving the performance, the weight per unit and the produced quantity of the wastes are reduced and the trend to thinning, lightweight and multifunctional packaging is realized.

Description

technical field [0001] The invention belongs to a packaging material and a preparation method thereof, in particular to a thinning and lightweight packaging material and a preparation method thereof. Background technique [0002] With the improvement of people's quality of life, the demand for detergents continues to increase, driving the prosperity and development of the detergent market.
