Embodiment 1

[0022]The material is first mixed, and the process method is substantially the same as the existing mixing method, and a uniform dry mixture is mixed from a high-speed mixer and a cooling mixer, and the specific process is as follows.

[0023](1) 100 parts of PVC resin, 2.5 parts of stabilizer thiolmetin, 181,18 parts of the plasticizer to terephthalate during rotation of high-speed mixer;

[0024](2) When the temperature of the high-speed mixer is raised to 75-80 ° C, 25 parts of ACR-G-VC copolymer resin, 15 thermoplastic elastomers TPVC, 0.8 parts of lubricant RGH-4; TPVC has traditional cross-linking High elasticity, aging resistance, and oil resistance of the vulcanized rubber, and the compatibility with PVC is better, and also has the characteristics of convenient ordinary plastic processing, the processing method is wide, and it is convenient for extrusion, blow molding. The return flexibility is greatly stretched, but the amount of addition is too large, the stiffness and intensity...

Embodiment 2

[0031]Embodiment 2 is generally the same as the technical solution of the first example, and the difference is the composition of the component:

[0032]All of the components are: 100 parts of the PVC resin, 28 parts of the ACR-G-VC copolymerization resin, 12 parts of TPVC thermoplastic elastomer, 181 2.3 parts of the stabilizer thioliometry, 2 plasticizer 2 19 parts of octyl, internal lubricant RGH-40.8 parts, 0.3 parts of the outer lubricant polyethylene wax, and 1.5 parts of the antifogramine monostearate.

[0033]Finally, a sleeve label film having a thickness of 0.025 mm was performed, and the lateral tensile strength was 29.3 MPa, and the longitudinal tensile strength was 42.4 MPa; its transverse fracture elongation was 862.1 MPa, and the longitudinal fracture elongation was The lateral tear strength is 667.8 MPa, and the longitudinal tear strength is 272.1 MPa; the haze is 3.3%.

Embodiment 3

[0035]All of the ingredients are: 100 parts of the PVC resin, 30 parts of the ACR-G-VC copolymerization resin, 10 parts of TPVC thermoplastic elastomer, 181 2 parts of the stabilizer thiometry tin, and 2 plasticizers. 20 parts of octyl, internal lubricant RGH-41.0 parts, 0.5 parts of the outer lubricant polyethylene wax, and 1.5 parts of the antifogramine monohydrate.

[0036]Finally, a sleeve label film having a thickness of 0.025 mm was performed, and the lateral tensile strength was 28.7 MPa, and the longitudinal tensile strength was 43.4 MPa; its transverse fracture elongation was 860.7 MPa, and the longitudinal fracture elongation was The lateral tear strength is 669.9 mPa, the longitudinal tear strength is 273.4 MPa; the haze is 3.3%.

[0037]As can be seen from the above data, the tensile strength of the cold absorbing label film using the above process process can satisfy the packaging requirements of the small rod shape, columnar or container class such as a certain long-distance...

Abstract

The invention discloses a PVC cold-shrinkable sleeve label film and a preparation method. In the traditional PVC production process, TPVC thermoplastic elastomer and ACR-g-VC copolymer resin are blended and added, and the materials are prepared by a high-speed mixer and a cooling mixer. Mixed into a uniform dry blend, the dry blend is plasticized and extruded by a single-screw extruder, and blown into a tubular film product of the required size by a blown film head. TPⅤC has the high elasticity of traditional cross-linked vulcanized rubber, and has good compatibility with PVC. At the same time, it has the characteristics of convenient processing and wide processing methods of ordinary plastics. It is convenient for extrusion, blow molding and other processing methods. After a large stretch Resilience; ACR‑g‑VC is a PVC blending modifier, which can improve the toughness and elongation at break of PVC resin, improve impact resistance and other properties; therefore ACR‑g‑VC copolymer resin and TPVC Blending and adding can not only maintain a certain resilience, but also ensure the toughness and mechanical strength of PVC resin.

Description

Technical field[0001]The present invention relates to the field of PCV tag film, and more particularly to a PVC cold receiving sleeve label film and a preparation method.Background technique[0002]Cold and shrink packaging, also known as stretch packaging, a new packaging technology developed based on heat shrink packaging, absorbs the advantages of traditional heat shrinkable film packaging and stretch film, regardless of packaging effect, packaging cost savings , There is a clear advantage in terms of packaging speed, widely used in food and beverage, household appliances, chemicals and construction industries. Thin film cold shrinkage is a term relatively thermally shrunk, is a pouch or a cylindrical elastic plastic film, and after being stretched by manual or cold absorbing packaging machine, the upper sleeve is placed on the package, and the film itself is used. Back to the elastic, wrap the items. The cold-shrinkable package does not need to heat, the energy consumed is only on...
