6 Microns Aluminum Foil Suitable For Flexible Packaging
Aluminum foil packaging bag material composition: pet/opp+aluminum foil+cpp/pe, nylon+aluminum foil+cpp/pe, aluminum foil packaging bag material is generally suitable for composite bags with more than three layers, due to the characteristics of aluminum foil double-sided electronics, aluminum foil material can only Put in.
O state aluminum foil, there should be no oil spots on the surface, and the water-brushing test on the surface should not be less than Grade B.
The test method of aluminum foil brushing performance is to use different liquids to wet the surface of a fixed material.
According to the principle of different characteristics, choose three different test liquids to brush the surface of the aluminum foil to determine the surface of the aluminum foil.
The degreasing grade of the noodles.
Test the surface cleanliness of flexible packaging aluminum foil under normal temperature conditions. Double aluminum foil selects the dark side for inspection. Peel off the aluminum foil of the outer ring at least 3mm thick. First dip a cotton ball into the prepared test solution (distilled water) and brush the test surface along the width direction of the aluminum foil. Tilt the aluminum foil 30°~50° (vertical direction) to observe the streamline shape of the aluminum foil surface, if the test solution is streamlined When the wetted area basically does not shrink, it indicates that the water brush test of the tested aluminum foil has reached the corresponding level of the test liquid
The wetting tension value is a concrete manifestation of the size of the oil stain on the surface of the original aluminum foil substrate. Wetting tension value reaches
Less than required, the ink will not adhere well to the original aluminum foil substrate during printing, resulting in printing
Uneven text patterns: To achieve a clear and complete text pattern printing effect, it must be monitored
For the surface oily condition of the original aluminum foil, use the original aluminum foil whose surface tension value fully meets the requirements.
Jumbo Aluminum Foil Rolls For Food a way to keep food fresh in cold storage. It is safe and secure, because food has its own shelf life, and aluminum will not enter the food
