PURPOSE:To provide an adhesive containing chlorinated polypropylene and specific components such as paraffin wax, etc., and giving a laminated material useful as a press-through pack for the packaging of drug, etc. by firmly bonding a polypropylene base with an aluminum foil. CONSTITUTION:The objective adhesive is prepared by compounding (A) 15- 40wt% of a chlorinated polypropylene, (B) 2-8wt% of paraffin wax, (C) 50- 80wt% of an aromatic hydrocarbon (e.g. benzen) (D) 0-7wt% of an alcohol (e.g. methyl alcohol), (E) 0-7wt% of an ester (e.g. ethyl acetate) and (F) 0-7wt% of a ketone (e.g. acetone). The adhesive is applied to a polypropylene base or aluminum foil base, and both bases are bonded together to obtain a laminate. EFFECT:When the adhesive is applied to the polypropylene base or the aluminum foil base and dried and wound to a continuous roll, the obtained film has high slippery and is free from blocking tendency. |
