Question:

What are the specifications of DNP aluminum plastic film?

Answer:

The division of specifications is as follows. 1. Apperance. It should be smooth, flat, bright and has even thickness and same transparency. Do not permit adequate plastifing of resin in raw material because of low processing temperature. Stripping "water wave" or slicing "cloud and mist" are formed on the surface of thin film. Bubble, perforation and rupture are not allowed. Impurities that are over 0.6mm are not allowed. Do not allow over 2mm particles and spot adjunct formed because of adequate plastifing of resin. Do not allow the existence of obvious "stripe". The unconspicuous "stripe" means that tear by hands in door temperature(the distance between two fingers is 1cm, like the gesture of tearing cloth). It takes on zigzag shape instead of straight line during tearing. Allow the existence of a small amount of live fold. Insertion and fold are neat(it means that volume header of a bundle of thin film is neat). 2. Thin film should be kept in a cool and dry room. Do not squeeze as far as possible. The distance away from the heat source is not less than 1m. The effective quality assurance period is one year. 3. Width (fold diameter refers to the film width when it is not torn, double layer) is greater than 1500 mm thin film. Deviation of +0.005mm and -0.005mm is allowed. Thick road with 20mm shall not be more than two. Thickness is not less than 0.08mm.
The specifications of DNP aluminum plastic film: Aluminum plastic plate can be roughly divided into interior decoration board and exterior decoration (curtain wall) board. The specification of aluminum plastic plate used in interior decoration is about 1.22m×2.44m×3mm. The thickness of exterior decoration is about 4mm. The size is not fixed, and they are generally customized.
a. Total thickness 3mm, 4mm, 6mm. Width: 1220mm, 1500mm. Length:1000mm, 2440mm, 3000mm, 4000mm, 6000mm. Aluminum plastic board with 1220×2440mm size is called standard board. Aluminum laminated films are thin film. PP and PET are made from vacuum steaming aluminum plating layer. Aluminum foil film is a kind of film made by compounding aluminum foil and plastic thin film. The aluminium coated layer is thin. Thickness is 300-400 angstrom. Aluminum foil is around 0.01mm.
