Description
Technical field
The invention belongs to acceptable packaging material technical field, press solidly particularly to a kind of cold punching
Body medicinal composite hard sheet.
Background technology
PVC plastic uptake and medical aluminum foil PTP is used to carry out heat seal in existing drug packaging industry
Packaging, there is the obstruct performance deficiency such as water vapour, oxygen, medicine, health product, food in PVC
The resting periods such as product are short, and the light transmission of PVC can not effectively intercept ultraviolet, and at purple
Outside line is the most aging under irradiating, and produces toxic gas.Although China's pharmaceuticals industry and health product,
Food service industry develops rapidly, and drug packing material have also been obtained and develops rapidly, but industry at present
The hot belt type cold stamping composite hard sheet structure of interior existence is nylon layer (both aramid layers), aluminum
Layers of foil, after molding, hot pressing seals with plastic uptake PVC, and this series products is easily made during cold stamping
Becoming causes aluminium foil layer damaged in layering and punching course between nylon layer and aluminium foil layer, and impact is produced
Product shelf-life and reduction production efficiency.Additionally, the material property in existing drug packing material
Typically, 3003 alloys or 8011 alloys are generally used such as the aluminium foil in drug packing material.With
The aluminium foil of 3003 alloy production, has good punching performance, but due to Mn in alloy
Constituent content is too high, and when carrying out homogenizing annealing, crystal grain is easily grown up, and is being rolled down to into
During product thickness, surface inevitably there will be coarse-grain striped, and impact is normal to be used.Another
Aspect, due to the characteristic of 3003 alloys self, the intensity of material is higher, to rolling equipment with
And the loss of punching device is relatively big, simultaneously need to add substantial amounts of copper, manganese metal, increase enterprise
The production cost of industry.With the tableware aluminium foil of 8011 alloy production, although 3003 can be overcome
The some shortcomings of alloy, but due in 8011 alloys alloying element content relatively low, but performance is inclined
Soft, be not suitable for high-speed punching, and the punching degree of depth is not enough, its range is by the biggest limit
System.
