What Are The Characteristics Of The Materials For Packaging Medicines In Blister Packaging Machines?
Sep 05, 2022
Our company's blister packaging machine can be used for packaging of various materials, among which PTP plastic cardboard is the most commonly used PVC cardboard. Although PVC has many advantages, such as good quality and low price, it is not very good in terms of moisture resistance, mildew resistance, water vapor resistance, and oxidation resistance. In addition, the production or use of PVC has long-term environmental and biological effects. At present, foreign developed countries have begun to ban and restrict the use of PVC blister packaging, which requires new packaging. Plastic blister must be synonymous with oxygen and water, with good performance to ensure the effectiveness of drugs without oxidative deterioration, calcium chloride, molds, etc. etc., especially traditional Chinese medicine, especially the most sensitive.
In order to improve the defects of PVC, we are currently producing blister packaging machines suitable for PVC composite sheet applications. This kind of composite sheet is mainly produced from PVC rigid sheet and one or more new polymer materials, films and sheets by extrusion, compounding, coating and other methods.
At present, the pressure-sensitive adhesives used in flexible pharmaceutical packaging composite materials have been replaced by polyurethane adhesives, mainly ester-soluble polyurethane adhesives. These adhesives are two-component adhesives, which are mainly modified by hydroxyl-containing polyurethane polyol, polyether or polyester polyol, polyester, and aromatic polyisocyanate. The curing agent is aromatic isocyanate and trimethyl methacrylate. alkane-based compounds. Welcome to inquire about our blister packaging machines for multi-packaging material applications.
