Description

Deoxidizer packaging film and preparation method thereof
Technical Field
The invention relates to the technical field of packaging materials, in particular to a deoxidizer packaging film and a preparation method thereof.
Background
The deoxidation package (FOA) is a technology which uses a deoxidizer which can generate a chemical reaction with oxygen or catalyze the chemical reaction of oxygen in a sealed packaging container to remove free oxygen in the packaging container so that the packaged object can be stored in a state of low oxygen concentration (oxygen is less than 0.1%) or even no oxygen.
The packaging material for implementing deoxidation packaging is required to have good air tightness, particularly high barrier property to oxygen, and specifically required to have the oxygen permeability of less than 20mL/(m2 & 24h & 0.1MPa at the temperature of 20 ℃). The packaging material or container preferably has a strength to avoid unsightly appearance due to shrinkage caused by negative pressure. At present, the deoxidizer uses a through, single-prevention or multi-prevention packaging material, and when the deoxidizer is applied to a dry environment product, moisture carried by a deoxidizer raw material is easily absorbed and dissipated by the dry environment due to air holes of the packaging material, so that the performance of the deoxidizer is poor, and the oxygen concentration in a package cannot be effectively reduced to a safe range.
For products with requirements on the appearance of the packaging container, the proportion of oxygen and carbon dioxide released by a displacement type deoxidizer of a common packaging material is unbalanced and unstable, so that the interior of the packaging container is in a negative pressure state easily; thereby affecting product quality and appearance.

step two, adding a needle roller punching device on the compression roller compound machine, wherein the needle roller is required to be as follows: punching a PE film in the semi-finished product I prepared in the step one to prepare a semi-finished product II, wherein the outer diameter of a needle roller is 100mm, the inner diameter of the needle roller is 60mm, and the length of a needle is 9 mm;
thirdly, gluing the punched PET film by using a gluing net wire roller, drying the PET film in an oven, bonding the PET film with the other surface of the oil-resistant waterproof paper in the semi-finished product II prepared in the second step, and drying the PET film in a drying room for 48 to 72 hours to prepare a semi-finished product III;
and step four, punching the PET film in the semi-finished product III prepared in the step three by using a needle roller punching device to prepare a finished product.
Wherein, the oil-proof and waterproof paper is not punctured by the punching in the second step and the third step.
Preferably, the corona treatment process in the first step is as follows: the speed is 100m/min, the power is 4200KW, and the off-machine test corona value is more than 38 dyne.
Preferably, in the second step, the perforating speed is 80-90m/min, and the pressure of the press roll compounding machine is 0.2-0.25 MPa.

in the invention, the oil-resistant and waterproof paper is not punctured by punching in the second step and the third step, so that the powder leakage phenomenon of the deoxidizer package is avoided, the package can directly contact with the contents, and no dust is leaked. Meanwhile, the oil-resistant and waterproof paper can prevent moisture and oil in the contents from corroding the deoxidizer, so that potential safety hazards and hazards such as content pollution caused by the leakage of the deoxidizer are avoided. Meanwhile, the perforation aperture is too thin and cannot ensure air permeability, the too thick aperture can cause leakage of the deoxidizer, the too small perforation array can affect the strength of the package, and the too large perforation array can affect the moisture absorption effect.
