Since the stretched film needs to be heated and then stretched for use, a special shrinking furnace is needed, and energy is wasted. At present, there is no one with high puncture resistance, good shrinkage and certain shrinkage stress, stretching and stretching. During the shrinking process, the film does not produce holes, and it can be stretched by mechanical force at room temperature. The cold stretched film used

Embodiment 1
[0014] First, mix 38% of LLDPE1018FA, 61% of MVLDPE1018HA, and 1% of PA10063 by weight percentage to make the outer layer raw material, and mix 72% of ELITEA59999.02, 18% of PP6102, and 10% of LLDPE1018FA by weight percentage Stir evenly to make the middle layer raw material, mix 55% MVLDPE1018HA, 43% LLDPE1018FA, 1% LDPE105, and 1% PA10063 by weight percentage to make the inner layer raw material, and then mix the outer layer raw material by weight percentage Mixed material, middle layer raw mixed material, and inner layer raw mixed material are compounded according to 30% of the outer layer, 40% of the middle layer and 30% of the inner layer. Produce the required film.
Embodiment 2
[0016] First, stir 41% LLDPE1018FA, 58.5% MVLDPE1018HA, and 0.5% PA10063 by weight percentage to make the outer layer raw material, and stir 69% ELITEA59999.02, 25% PP6102, and 6% LLDPE1018FA by weight percentage Evenly make the middle layer raw material, mix 50% MVLDPE1018HA, 49% LLDPE1018FA, 0.5% LDPE105, 0.5% PA10063 by weight percentage to make the inner layer raw material, and then mix the outer layer by weight Materials, middle layer raw materials and inner layer raw materials are mixed according to 30% of the outer layer, 40% of the middle layer and 30% of the inner layer. required film.
Embodiment 3
[0018] First, mix 40% LLDPE1018FA, 58.5% MVLDPE1018HA, and 1.5% PA10063 by weight percentage to make the outer layer raw material, and mix 70% ELITEA59999.02, 22% PP6102, and 8% LLDPE1018FA by weight percentage Stir evenly to make the middle layer raw material mixture, mix 53% MVLDPE1018HA, 44% LLDPE1018FA, 1.5% LDPE105, 1.5% PA10063 by weight percentage to make the inner layer raw material mixture, and then mix the outer layer raw material by weight percentage Mixed material, middle layer raw mixed material, and inner layer raw mixed material are compounded according to 30% of the outer layer, 40% of the middle layer and 30% of the inner layer. Produce the required film.
[0019] After several tests, the company lowered the stretching temperature continuously by replacing different components, and finally concluded that within the scope of the components described in the present invention, the purpose of stretching at room temperature can be achieved, and its puncture resista...

Abstract
The invention relates to a cold-drawing film. The cold-drawing film comprises three parts in percentage by weight: 30% of an outer layer, 40% of a medium layer and 30% of an inner layer. The invention further provides a production method of the film, wherein the production method comprises the following steps: step I, mixing materials; step II, batching materials; and step III, blowing a film. The film which is produced according to the component formula and the production method disclosed by the invention has higher puncture resistance, good shrinkage and certain shrinkage stress, so that holes are not formed in the film in the drawing and the shrinking processes. Moreover, the cold-drawing film can be used for drawing only by virtue of mechanical force under the normal temperature.
Description
technical field [0001] The invention relates to the field of film production and processing, in particular to a cold stretch film and a production method thereof. Background technique [0002] Blowing film (Blow Membrane) is a plastic processing method, which refers to a plastic processing technology in which plastic particles are heated and melted and then blown into a film. If it is a film blown out of new materials, the color is uniform and clean, and the finished product is stretched well. If the plastic particles made of recycled waste plastics are usually added with pigments when made into a film, the resulting film may be unevenly colored, brittle and easily broken, and the price is relatively low. The blown film materials produced by professional film blowing machines are suitable for various high-grade film packaging. This film can be widely used in light and heavy packaging due to its good barrier properties, freshness preservation, moisture resistance, frost res...
