In the pharmaceutical industry, Clear Boxes packaging is one of the ideal forms of packaging the products, such as tablets, capsules and lozenges. In Vancouver, it is popular because it offers provide barrier protection for shelf life requirements and a degree of tamper resistance. Another packaging medium, the high-density polyethylene (HDPE) pill bottle is also favored for its impact resistance, economical value and ability to withstand high temperature. In this article, we will see brief manufacturing processes of these packaging pharmaceutical materials. Blister packs consist of two parts the cavity or a pocket and (ii) the lid or a seal of aluminum foil or plastic. Polyvinyl Chloride (PVC) is mainly used for its cost effectiveness and flexibility.
Cyclic olefin copolymers (COC) or polymers (COP) are also used for the same purpose. Manufacturers have two approaches of forming the blisters. In the first approach of thermoforming, the pre-heated plastic is fed into a forming station on the blister line. Now, a high pressure will form the cavity into a negative mold, which is further allowed to cool and become arid cavity. Then, the tablet is filled into the cavity and sealed off with a malleable material. In the second approach of cold forming, the tablet is pressed between aluminum-based laminated films. This allows an extended product expiry date, but it is much slower than thermoforming process. Cold forming also requires strict quality maintenance practices. HDPE pill bottles are created from polyethylene thermoplastic, a petroleum product.
Manufacturers start the process with the creation of wood-plastic composites. They would three tanks a tank with ethane a mixing tank where the heated ethane is passed into, and a tank with benzene to facilitate ethane polymerization. Then, it is further treated to get the high-density polyethylene. The procedure of bottle blow molding follows next extensively. There are three main types of blow molding: extrusion blow molding, injection blow molding, and stretch blow molding. Some of the materials essential for the process include an airtight heated tank, series of air compressors, a circular razor and a hopper. Finally, it is allowed to cool and the preparation of HDPE pill bottle is completed with polishing and buffing off any edges. To summarize, these blister packs and HDPE bottles have been convenient packaging materials in Vancouver. Many reputed manufacturers specialize in producing them as well.
