Pressure and temperature are formed is too small will be significantly enhanced. Many factors affect the flowability, to assess the flowability of certain materials, the composition must be specifically analyzed. Liquidity factors.
Medicinal plastic bottles trends: multi-layer extrusion vial and the vial medical plastic bottle security trends: security and multilayer extrusion bottle bottle: Source: pharmaceutical and device industry Chemease networks in developed countries are very pay attention to packaging development. The following new packaging materials, development and production of new bottles, is expected to completely change the traditional past of Medical Device packaging, make Medical Device product packaging has leapt to a new level. Child-resistant cap formula pull plastic bottles bottles are the most common drug packaging, it can not only store solid drugs (such as tablets), it can also be used to store liquid agents (such as medicine). 1750s, most countries in the world production of glass bottles for the bottle material, cover the metal swing-open lid. The biggest drawback of such a bottle is: impatience haul, high crushing ratio, caps closed lax easily understood cause leakage, microbial contamination, built liquid mildew. This old-fashioned glass bottles pharmaceutical companies have rarely been adopted in Western countries, replaced by a highly transparent polyester material, plastic bottles and pull the cover. These newly developed bottle is not only transparent, but resistance to drop, impact resistance, biocompatibility, and some due to the use of technology to pull the cover open is very convenient. However, the pull-lid transparent plastic bottle also has some disadvantages: vulnerable children easily open, which could result in accidental poisonings. For this reason, some foreign manufacturers have to design a child-resistant cap formula pull plastic bottles. Plastic series, called "MAC lid" pull bottle cap is available now in the United States.
Moisture and oxygen impermeable material of certain new drugs and sophisticated equipment in a humid environment is perishable or damaged, resulting in reduced efficacy or even failure, as well as precision equipment performance changes. The packaging of these products can be completely isolated from moisture and oxygen material should be used. Not long ago, the US city of Pittsburgh Alcoa flexible packaging company developed and launched a new universal aluminum - plastic composite packaging material (trade name COLDFORM). The new packaging material can be used as packaging material directly medicines, syringes, disposable contact lenses and a variety of precision instruments products. According to the company the person in charge, COLDFORM is machined from aluminum foil thicker than the average percent of aluminum foil, polyvinyl chloride (PVC), polyurethane and other polymer film made of dense excellent new composite material. COLDFORM use packaging made from basic to avoid infiltration of moisture and oxygen, it can greatly improve the shelf life of the product. Alcoa's another new composite materials for the packaging Medical Device "Safety-pakPlus". It is understood that the use of new packaging materials and micron aluminum foil terephthalate (PET) film composite poly-micron processing.
