In recent years, the aluminum-plastic blister packaging of drugs has been developed rapidly in our country, because of the characteristics of this kind of packaging has a long storage period, easy to carry, more and more welcomed by pharmaceutical enterprises and consumers, is gradually replacing the traditional glass bottle packaging and bulk packaging, and has become the mainstream of solid drug packaging.

Aluminum-plastic blister packaging, also known as blister eye packaging, is a new solid drug packaging form. After the transparent plastic hard piece is formed, the tablets, pills, capsules and other solid drugs are filled in the groove, and then heated together with the aluminum foil coated with adhesive to form an independent sealed package.

At present, many domestic solid drugs are still packaged in glass bottles. Although they can protect against light, moisture and oxidation, the packaging capacity is large and the scientific and technological content is not high. For special drugs with higher requirements, this traditional packaging form can not effectively prevent drugs from deliquescent mildew, which is also an important reason for the rapid removal of large capacity brown glass bottle packaging in recent years. Compared with bottled medicine, ChengDa CD - 250 aluminum-plastic blister packaging machine for the production of capsule blister packaging, tablets aluminum-plastic blister packaging larger advantage is easy to carry, can reduce the pollution in the process of carrying and taking drugs, and blister packaging in gas barrier property, moisture permeability, health, safety, production efficiency, dose accuracy and extend the shelf life of drugs and so on also has obvious advantages.

The good barrier performance of blister packing is due to the choice of aluminum foil and plastic hard sheet. Aluminum box has a highly dense metal crystal structure, good barrier and shading property; Plastic hard piece should have enough to oxygen, carbon dioxide and water vapor of the barrier performance, high transparency and mechanical strength such as not easy to crack characteristics. At present, the more common packaging materials for pharmaceutical blisters are PVC sheets and PVDC (polyvinylidene chloride).

PVC has good compatibility performance, easy molding and sealing, low price, transparency, barrier and mechanical strength can basically meet the requirements of drug packaging, but the ability to block water vapor and thermal stability is poor, for moisture-proof requirements of higher drugs, PVC is not satisfactory.

PVDC has high molecular density, high crystallinity and transparency, and good weather resistance. PVDC film is a kind of film with good barrier performance at present. The barrier of PVDC film with the same thickness to oxygen is 1500 times that of PE and 100 times that of PP and PET. And it for water vapor barrier performance is higher than PVC, is the ideal material for blister packaging. Multilayer composite hard film made of PVDC and other film materials or coatings, such as PVC/PVIX, BOPP/PVDC, PVC/PVDC/PE, PVDC/OPP/PE, etc., oxygen permeability, moisture permeability, moisture resistance, barrier performance are significantly higher than the single material film.

Another kind of blister packing material is vacuum aluminum plating film, which is a kind of film that precipitates aluminum vapor on the base film under high vacuum state. At present, PET, CPP, PVC, OPP, PE and so on are widely used. Vacuum aluminized film as the base film, in addition to the characteristics of the original base film, aluminized film also has beautiful decorative and better barrier performance, light transmittance, oxygen permeability and moisture permeability are only a few tens of one or even one percent of the original base film, is also one of the key development directions of blister packaging materials in the future.

Another advantage of blister packaging is the automatic packaging process to a large extent to ensure the safety of drug packaging. CD-250 Automatic Aluminum Plastic Blister Packing Machine, Capsule Blister Packing Machine, Tablet Blister Packing Machine includes the forming of blister, medicine filling, sealing, molding of outer packing carton, folding and inserting of manual, packing of blister plate and sealing of carton. The whole process is completed at one time, safe and hygienical. Professional models in addition to a high degree of automation, there are a number of safety detection devices, including the identification and detection of packaging boxes and instructions, can greatly improve the safety and hygiene, and can effectively reduce the misloading of drugs.
