Embodiment 1

[0022] Such as figure 1 As shown, a kind of production technology of the PVC heat-shrinkable film packaging bag that is used for tobacco cigarette of the present embodiment is characterized in that, comprises following processing step:

[0023] (1) Preparation of raw materials: The raw materials for the production of this PVC heat shrinkable film include the following components, in parts by weight: 80 parts of PVC resin powder, 2 parts of NCP-2 auxiliary agent, 4 parts of glyceryl monostearate, adipic acid 3 parts fat, 12 parts talcum powder, 4 parts Houttuynia cordata extract, 3 parts ESC-1010 antioxidant;

[0024] (2) Primary mixing: put PVC resin powder, NCP-2 additives glyceryl monostearate, adipate and talcum powder in the raw materials and stir in a blender at a stirring temperature of 70°C and a rotating speed of 80rpm. Wherein the stirring time length is 20min;

[0025] (3) Secondary mixing: add Houttuynia cordata extract and antioxidant to the mixed material obtain...

Embodiment 2

[0030] Embodiment 2: all the other are the same as Example 1, except that the duration of stirring in the step (2) is 25min, the stirring temperature is 75°C, and the rotating speed is 70rpm, and the duration of stirring in the step (3) is 12min. The temperature is 90°C, the rotating speed is 180rpm, and the reaction time of the reactor in the step (4) is 1.5h. In the step (5), the material is cooled to 30°C through the cooling air ring of the double tuyere, and the step (6) The transverse stretching ratio is 6, the longitudinal stretching ratio is 6.5, and the hole diameter of the perforated holes is 2.5cm.

Embodiment 3

[0031] Embodiment 3: all the other are the same as Example 1, the difference is that the duration of stirring in the step (2) is 30min, the stirring temperature is 80°C, and the rotating speed is 80rpm, and the duration of stirring in the step (3) is 15min, stirring The temperature is 100°C, the rotating speed is 160rpm, and the reaction time of the reactor in the step (4) is 2h. In the step (5), the material is cooled to 40°C through the cooling air ring of the double tuyere. In the step (6), The transverse stretching ratio is 7, the longitudinal stretching ratio is 6, and the hole diameter of the perforated holes is 2.5 cm.

[0032] After the above process steps, the PVC heat shrinkable film sample was taken out, and the following data were obtained:

[0033]

[0034] From the above data, it can be seen that the product obtained by the present invention can maintain the characteristics of large heat shrinkable film elongation, good self-adhesiveness and high transparency,...

Abstract

The invention discloses a production technology of a PVC heat shrinkage film packaging bag for tobacco and cigarette and relates to the field of heat shrinkage film production technology. The production technology comprises seven technological processes, namely raw material preparation, primary batch mixing, secondary batch mixing, high-temperature mixing, granulation and extrusion moulding, two-way stretching and finished product packaging. The technological process is simple, and nontoxic and harmless chemical products are adopted for manufacturing. The prepared PVC heat shrinkage film material has high shrinkage uniformity and high shrinkage, is environment friendly shrinkage film, has low-temperature resistance and high-temperature resistance, has obvious using effect, is pollution-free, has high market value, and is worthy of promotion.

Description

technical field [0001] The invention relates to the field of heat-shrinkable production technology, in particular to a production technology of a PVC heat-shrinkable film packaging bag for tobacco cigarettes. Background technique [0002] Heat shrinkable film is used for sales and transportation of various products, and its main function is to stabilize, cover and protect products. Shrink film must have high puncture resistance, good shrinkage and certain shrinkage stress. Heat shrinkable film is widely used in: food, medicine, disinfection tableware, stationery, craft gifts, printed matter, hardware and plastic products, telephone, Outer packaging of various products such as electronic appliances. PVC heat-shrinkable film is made of ethylene-based PVC resin mixed with more than a dozen auxiliary materials and then inflated twice. It is characterized by good transparency, easy shrinkage, high strength, shrinkage rate can be adjusted freely according to user needs, and stron...
