FFS class SBS consists of two parts, Top Web and Bottom Web. Li Tong, the materials used for Top web are mainly coated or uncoated Tyvek and medical breathable paper, films with special easy-release coatings, etc. 
The Bottom Web is mainly soft-blown film of various structures. The common structures in China are PP/PE, PA/PE, Surlyn/EVA/Surlyn.

The first structure is a polypropylene composite film, which is economical. The nylon film in the second structure has high strength and puncture-resistant inkjet printing. The Surlyn layer in the last structure can increase the softness of the composite film and formability. Beautiful appearance. FFS class SBS , the biggest advantage is a high degree of automation, high efficiency, and the cost is not high inkjet printing, but it is not suitable for complex structure or high requirements of equipment packaging.

The hard blister-cover type SBS is also composed of two parts: box and cover disc printing, in which the materials used in the box are mainly PS (polystyrene), PVC (polyvinyl chloride), PETG (cyclohexanol modified) Polyester, which can provide heat sealing properties and some other processing properties that PET does not have. Only two companies in the world can produce the resin at a relatively high price.) And PC (polycarbonate, which is very rare in China, is expensive, Used on the packaging of three types of products)

Tyvek AsuronTM, which improves the existing Integrity Tyvek thickness and unevenness, provides a higher level of protection for a wide range of medical devices. The current Tyvek has four grades, namely Tyvek 2FS, 1059B, 1078B and Asuron, which are 56.0g/m2, 64.4g/m2, 74.6g/m2 and 68.0g/m2, respectively. Tyvek is used in MDSP mainly because of its good water resistance, air permeability and excellent physical and mechanical properties such as tensile, tear and puncture resistance, and it is widely adapted to the existing conventional sterilization methods, including Ethylene oxide (EO), high pressure steam, electron beam, gamma ray and X-ray special printing, except for high temperature steam sterilization under special conditions. 
MDSP also belongs to the category of flexible packaging based on paper-plastic materials, and its important difference from ordinary flexible packaging is that medical device products have very high requirements on packaging materials, in addition to meeting the basic packaging performance of conventional protection and isolation of the external environment. Emphasis is placed on the continued stability of material properties, as well as the compatibility with sterilization methods, microbial barrier properties and non-toxicity of the material, which requires SBS to be produced by professional MDSP manufacturers. The 2006 edition of ISO 11607 also specifically stipulates that MDSP manufacturers should confirm the PSBS production process to ensure that its quality is continuous and stable, which is enough to prevent companies engaged in general industrial products and food packaging from entering the MDSP field. MDSP also belongs to the category of flexible packaging based on paper-plastic materials, and its important difference from ordinary flexible packaging is that medical device products have very high requirements on packaging materials, in addition to meeting the basic packaging performance of conventional protection and isolation of the external environment.

Of course, because the sales target and the object of use of medical device products are relatively fixed and extremely professional, they do not attach great importance to the design of the product packaging design, which is also designed with ordinary soft packaging (such as high-end food, medicine and fine crafts packaging). The difference lies in the fact that the packaging design of medical device products does not pay attention to the vivid color and the complexity of the pattern, but merely a reminder of the nature of the label. But MDSP, like pharmaceutical packaging, has a surprisingly high labeling requirement because it facilitates product traceability and guides the use of green printing, even when the product has serious quality problems.

As in most industrial sectors, the most powerful country in the MDSP sector is still the United States. This strong strength includes upstream strong raw material and plastic resin suppliers, midstream MDSP PSBS product manufacturers and downstream more powerful medical device manufacturer processes, as well as powerful supporting technologies and information services such as ASTM, ISO, Standards and regulatory agencies such as AAMI and FDA. Based on this fact, the current status of the global MDSP market is basically to introduce the status quo of the United States. Of course, in addition to the United States, Europe and Australia also have good MDSP PSBS suppliers and related machinery manufacturers.
