The present disclosure relates to an encapsulation adhesive film for a solar cell, comprising a transparent layer in contact with a cell sheet, and a first adhesive film layer in contact with the transparent layer, wherein raw materials of the first adhesive film layer comprise the following components: a resin and a colored filler with a mass ratio of 3 to 25: 1, a cross-linking agent accounting for 0.1 % to 5 % of the total mass of the resin and the colored filler, an auxiliary cross-linking agent accounting for 0.1 % to 1 % of the total mass of the resin and the colored filler, a coupling agent accounting for 0.1 % to 1 % of the total mass of the resin and the colored filler, a light stabilizer accounting for 0.1 % to 1 % of the total mass of the resin and the colored filler, and a photo initiator accounting for 0.1 % to 5 % of the total mass of the resin and the colored filler. The present disclosure can effectively prevent a white substance from overflowing.

MASKING TAPE AND ITS USE

ADHESIVE FILM FOR CUTTING WITH LASER WATER JET

BIAXIALLY-ORIENTED POLYPROPYLENE FILM WITH HIGH MECHANICAL STRENGTH

A biaxially-oriented film with high mechanical strength, which includes 69 to 94.99% by weight of a polyolefin, 5 to 30% by weight of a natural or synthetic resin having a softening point in the range from 70 to 170.degree.C, and 0. 01 to 1% by weight of a nucleating agent, based on the total weight of the film. A method for producing this film includes biaxially drawing the film at temperatures below the melting point of the polyolefin.
