In order to extend using period, there have many medicine requirements packing to accomplish now to be high as far as possible airtight.But general load mould packing or alveolitoid cover packing can only be accomplished this point in limited scope: gas or water vapour are owing to spread and can enter by carrier walls.The degree of this diffusion is no doubt relevant with the kind of the used plastics of carrier, but is the barrier that can not constitute the gas of one absolutely gas-tight and steam with a plastic carrier.Airtight in order to guarantee to accomplish, people know that available a kind of aluminium laminated film that contains makes carrier by cold shaping in recent years.From the packing outside inwards, this laminated film for example can be made up of the aluminium of OPA (orientation polyamide), the 0.045mm of 0.025mm and the PVC of 0.060mm, it includes aluminium foil and can guarantee airtight, the intensity that can make carrier that combines aluminium and plastic sheeting improves, and contemplated as people, in the cold shaping process, can prevent from aluminium foil to occur to cause the stretching peak value that tears.Experience points out for certain that also the cold shaping ability of described composite material is obviously than equivalent normal aluminium foil height.But it is the regulation that they do not meet existing relevant waste discharge that the wrapping carrier of this alveolitoid cover has a shortcoming, according to this regulation, this empty package that uses up has only to contain when them and just allows to do as a whole refuse when same material reaches 90% by weight at least and drain.And in the example that provides in the above, the content of aluminium just only about 57%.On the other hand, adopt pure aluminum foil also not have successful experience up to now in practice as the carrier of load mould packing or alveolitoid cover packing.
Task of the present invention at first is to develop the aluminium foil that has than shallow layer, and this aluminium foil must have the cold shaping performance of improvement and be specially adapted to alveolitoid cover packing, can be used as the high-air-tightness material that carrier is used.
Summary of the invention
According to coated aluminum foil of the present invention, above-mentioned task is to solve like this, aluminium foil has the thickness in 0.05 to the 0.3mm scope, and the coating surface of cavity side has one and is up to 0.35 but preferably be up to 0.30 friction coefficient according to what British Standard, Automobile Series (BS) 2782 was measured, and/or aluminium foil has at the coating surface of formpiston side and is up to 0.45 but preferably be up to 0.40 this friction coefficient.
Wherein the surface of cavity side preferably is made of a plastic layer.
According to a more excellent embodiment of the present invention, the plastic layer of formpiston side is that hot pressing is bonding and have from the thickness of 0.001 to 0.030mm scope.According to another more excellent embodiment of the present invention, above-mentioned this thickness but is preferably in 0.003 to 0.012mm scope in 0.003 to 0.020mm scope.
According to the more excellent embodiment of another one of the present invention, it is characterized by, the synthetic resin layer of cavity side is to be made of the thin protective paint layer of a thickness in 0.0005 to 0.020mm scope.
Another task of the present invention is to develop a kind of packing with high-air-tightness, particularly the alveolitoid cover is packed, this packing has the carrier of a planar materials, in an one flat site, make many pits so that admit packing material special as tablet, capsule etc. by the shaping of this material, and in this flat site smoothly in conjunction with the layer of aluminum sealed foil, thereby make the aluminium content of empty package reach a high as far as possible percentum.
This task is used according to of the present invention the packing and is solved, it is characterized by, carrier is made of a block of material, many pits are to make with cold forming method, but and be provided with the plastic layer of a pressurized adhesion at least at the concave surface of pit, carrier is made according to coated aluminum foil of the present invention by a slice in addition, thereby the aluminium content of empty package by weight can be greater than 80%, even can be more preferably greater than 90%.
