Machine For Manufacturing Masking Paper Tape Rolls

Machine For Manufacturing Masking Paper Tape Rolls

1.  150m/min high speed has already reached the international most advanced level.

2.   Rewind and unwind both adopt double position and equip with semi-automatic to connect paper device, The machine can change the rolls of base material nonstop, It will reduce the waste.

3.   When the double sides adhesive tape coat twice, it will effect the quality of products, but the technology of double sides coating meanwhile will solve the questions.

Polyethylene (PE) film--


The PE film has a large gas permeability, and as the density increases, its gas permeability is lowered. The PE film has moisture resistance and low moisture permeability. Polyethylene film (PE) can produce low-density, medium-density, high-density polyethylene and cross-linked polyethylene with different properties depending on the manufacturing method and control method.

Low density polyethylene (LDPE):
- Its density is about 0.92g/cm2. Low-density polyethylene film has good transparency and heat-sealing property, can be waterproof and moisture-proof; low tensile strength, large tensile elongation, easy to wrinkle, film of 0.03mm or less, tension control should be small, and tension everywhere It should be constant, especially when heated, it is more deformable, making it difficult to color. Therefore, when drying, the film surface temperature should not be too high (within 550C). According to different film forming processes, it can be divided into blown film (IPE), cast film (CPE), low foaming film and so on. The tensile strength and opening property of IPE film are better than that of CPE film. It can be used as food bag and garment bag for front printing. CPE film has uniform thickness, surface gloss, transparency and heat sealability ratio, PE is good, and can be printed on the front and back. However, the production cost is high; the CPE film is mainly used as the inner layer of the composite bag and the packaging of cosmetics, pickles and cakes; the low foaming film has good decorativeness, thick texture, and is not easy to be stretched and deformed, and is printed on the front side for use as a new year painting and trademark. And hand bags and so on.

Aluminized film (VMPET, VMCPP)--

 

Characteristics
(1) The amount of aluminum used is greatly reduced, energy and materials are saved, and the cost is reduced. The thickness of the composite aluminum foil is 7 to gpm, and the thickness of the aluminum layer of the aluminized film is about 0.05 n, and the aluminum consumption is about Aluminum foil is 1/140 to 1/180, and the production speed can be as high as 450m/min.
(2) It has excellent folding resistance and good toughness, pinholes and cracks are rare, and there is no cracking and cracking, so the barrier property against gas, water vapor, odor, light, etc. is improved.
(3) It has excellent metallic luster, and the light reflectance can reach 97%; and it can be processed by coating to form a color film, and its decorative effect is beyond the reach of aluminum foil.
(4) Partial aluminizing can be performed by shielding to obtain any pattern or transparent window, and the contents can be seen.
(5) The aluminum plating layer has good electrical conductivity and can eliminate the electrostatic effect; its sealing performance is good, especially when packaging the powdery product, it will not pollute the sealing part, and the sealing performance of the packaging is ensured. (6) It has good adaptability to post-processing such as printing and compounding.
Due to the above characteristics, the aluminized film has become a new type of composite film with excellent performance and economical appearance, and has replaced the aluminum foil composite material in many aspects. It is mainly used for vacuum packaging of flavor foods and agricultural products, as well as packaging of medicines, cosmetics and cigarettes. In addition, aluminized films are also widely used as bronzing materials and trademark label materials in printing.
