Characteristic
1， can significantly enhance photos， pictures of the color and contrast;
2， to prevent the dirty dirty fingerprints， or scratch photos， pictures and documents;
3， a large number of repeated exposure to the items need to be protected， such as restaurant menus， etc.;
4， make the photos， documents or documents stored for many years are like new， do not fade， no damage;
5， can protect the need to put in a long time outdoor items;
6， can prevent the photos， documents or documents in the course of transportation damage;
7， after plastic photos， documents or documents can be put in the water or other special conditions;
8， over the plastic document or documents increased strength and toughness.
Note
1， the environmental impact of plastic: plastic machine stable preheating time by the influence of ambient temperature， ambient temperature is high， plastic temperature can rapid equilibrium and the stability of the ambient temperature is low， fast heat dissipation， lamination temperature need longer time to achieve stable equilibrium. Avoid the boot after the temperature display just to the plastic temperature of plastic， because at this time plastic rollers by ripe yet stable equilibrium， but local temperature near the temperature reached lamination temperature. Generally speaking， preheating and stabilization time should not be shorter than 20 minutes. The design index of molding machine working environment for a 5~40 C， relative humidity is less than 80%， non corrosive gas. Therefore， the plastic packaging machine can work normally and seasonal climatic conditions， will not affect the plastic effect.
2， the rubber hardness influence on the plastic molding machine rubber hardness to shore 50 degrees. If the rollers for aging and other reasons caused by variable hard or cracking， will affect the quality of plastic， the plastic card plastic unstable， the need for timely replacement cots.
3， the plastic quality inspection by plastic sealed documents should be transparent， smooth， plastic sleeve and the card core should be firmly sealed as a whole. There is no "air filled" in the interlayer， no "fuzzy white print"， no oil， impurities and other undesirable phenomena. Several common abnormal phenomena and judgment， such as local prison closed should consider plastic temperature low such as plastic identification deformation wrinkle folding should be considered for plastic temperature is too high or pressure is too large such as interlayer bubbles or fuzzy printing white opacity should be considered for plastic sealing temperature is not suitable as a result of plastic adhesive spillover， should be considered for the plastic temperature is too high or too much pressure.
