Plastic packaging, a new favorite of health food

Plastic packaging, a new favorite of health food

2016-10-19 16:23

Aluminum-plastic blister packaging (also known as blister eye packaging) is a new type of solid drug packaging, which is widely used in health foods and pharmaceuticals at present. It develops rapidly in China. Because of its long storage period and convenient carrying, it is more and more welcomed by pharmaceutical enterprises and consumers, and is gradually replacing the traditional glass. Glass bottle packaging and bulk packaging have become the mainstream of solid drug packaging. _Advantage of blister packaging Blister packaging is to first absorb and shape transparent plastic sheets, then fill the grooves with tablets, pills or granules, capsules and other solid medicines and health food, and then heat and bond with aluminum foil coated with adhesives to form an independent sealed packaging. This kind of packaging is one of the most widely used and rapidly developing soft packaging forms in the health food industry and pharmaceutical industry. At present, many domestic solid drugs are still packaged in glass bottles. Although they can avoid light, moisture and oxidation, their packaging capacity is large and the content of science and technology is not high. For special health care products and medicines with higher requirements, this traditional packaging form can not effectively prevent the drug from dehydration and mildew, which is also an important reason why large-capacity brown glass bottle packaging is rapidly withdrawing from this field in recent years. Compared with bottled packaging, the biggest advantage of bubble cap packaging is easy to carry, can reduce the pollution caused by health products and medicines in the process of carrying and taking, and bubble cap packaging has obvious advantages in gas barrier, moisture permeability, health safety, production efficiency, dose accuracy and prolonging the shelf life of medicines. 。 Another advantage of blister packaging is that the full automatic packaging process maximizes the safety of packaging. Fully automatic blister packaging machine includes blister forming, drug filling, sealing, packaging carton forming, folding and inserting instructions, blister board boxes and carton sealing, the whole process is completed at one time, safe and hygienic. In addition to the high degree of automation, advanced models also have a number of safety detection devices, including the identification and detection of packaging boxes and instructions, which can greatly improve safety and hygiene, and effectively reduce the misloading of health products and medicines. Material selection determines the superiority of blister packaging. The good barrier performance of blister packaging is due to the selection of raw materials such as aluminium foil and plastic hard sheet. Aluminum foil has a highly dense metallic crystal structure, good barrier and shading properties; plastic sheets should have sufficient barrier properties to oxygen, carbon dioxide and water vapor, high transparency and mechanical strength not easy to crack. At present, the most commonly used medical blister packaging materials are PVC sheets and PVDC (polyvinylidene chloride). PVC has good compatibility, easy to form and seal, 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 products with higher moisture-proof requirements, PVC is unsatisfactory. PVDC has high molecular density, regular structure, high crystallinity and transparency, and good durability. At present, PVDC film has the best barrier performance. The oxygen barrier of PVDC film with the same thickness is 1500 times of PE, 100 times of PP and PET, and its water vapor barrier performance is also higher than that of PVC, which is the ideal material for bubble cap packaging. Material. Multilayer composite hard sheets made of PVDC and other film materials, such as PVC/PVDC, BOPP/PVDC, PVC/PVDC/PE, PVDC/OPP/PE, etc., are obviously higher in oxygen permeability, moisture permeability, moisture resistance and barrier performance than those made of single film material. The advantages of various materials are fused into one, which provides a material for bubble cap packaging. A cheap choice. Another kind of foam cover packaging material is vacuum aluminium coating, which deposits aluminium vapor on the base film under high vacuum. At present, widely used vacuum aluminium coating with PET, CPP, PVC, OPP, PE as the base film, besides the characteristics of the original base film, the aluminium coating also has beautiful decoration and better performance. Barrier performance, light transmittance, oxygen permeability and moisture permeability are only one-tenth or even one-hundredth of the original film, which is also one of the key development directions of foam cap packaging materials in the future.
