What are the commonly used plastic sheets for blister packaging

The sheet used for blister packaging is called rigid sheet or film, commonly used are: PET (polyethylene terephthalate) rigid sheet, PVC (polyvinyl chloride) rigid sheet, PS (polystyrene) rigid sheet. PS hard sheet has low density, poor toughness, easy to burn, and produces styrene gas (a harmful gas) when burning, so it is generally used to produce various industrial plastic trays. PVC hard sheet has moderate toughness and is not easy to burn. When burning, chlorine gas will be produced, which will have a certain impact on the environment. PVC is easy to be heat-sealed, and can be edge-sealed by sealing machine and high-frequency machine. It is the main raw material for the production of transparent plastic products. PET hard sheet has good toughness, high transparency, easy to burn, and does not produce harmful gas when burning. It is an environmentally friendly material, but the price is high, and it is suitable for high-end blister products. It is not easy to heat seal, which brings great difficulties to packaging. In order to solve this problem, people use a material called PETG ethylene glycol modified-polyethylene terephthalate, which has both the ease of PVC. Heat sealing, also has the high environmental protection and transparency of PET, but the price is higher.

The difference between blister and injection and blow molding

Blister packing: Plastic processing technology, the main principle is that after heating and softening the flat plastic hard sheet, vacuum is used to adsorb it on the surface of the mold, and it is formed after cooling, saving raw and auxiliary materials, light weight and convenient transportation.

Blow molding: The tubular plastic parison obtained by extruding nylon is placed in a split mold while it is still hot. After closing the mold, air is compressed in the parison to inflate the plastic parison and stick to the inner wall of the mold. mold to obtain various hollow products. The main products are: nylon casing film, bottle, jar, nylon tube, etc.

Injection molding: molding is mostly used for thermoplastics. It is similar to extrusion molding, the difference is that the molten plastic enters the closed mold through the nozzle, and the product is solidified and formed in the mold. More production of small boxes, daily necessities. Special-shaped parts, etc. It can also be used for hot plastic processing.

What is the material of PP blister material?

PP material is a kind of plastic, odorless, non-toxic, tasteless, high-density, milky white high-crystalline polymer without side chain, with excellent comprehensive performance. PP plastic material has the advantages of light texture, good toughness, good impact resistance, strong surface rigidity and not easy to be scratched. Cutlery, lunch boxes, etc.

The melting point of PP blister material reaches 167 degrees. It is the only material that can be heated in a microwave oven among all blister sheets. It is also a cold-resistant sheet, with a cold-resistant temperature of minus 35 degrees. Therefore, frozen food packaging, cold fresh For meat, cooked food, seafood and other food that needs to be refrigerated or heated, PP blister packaging is the choice of many businesses. PP blister is commonly used in daily life, such as: PP cooked food box, PP freezer box, PP pastry box, ice cream box, dumpling box, dumpling box, etc.
Sheet PP blister material is widely used in the food industry, and also used in electronic products. Conductive packaging products are used for packaging of electronic parts such as testing, TFT, optoelectronics, IC wafers, IC packaging, etc. to avoid contact with other charged items, resulting in Parts are damaged by sparks due to electrical friction.
PP blister thick board is used for industrial boards, storage racks, partitions, bottom plates, turnover boxes, etc. Modified PP plastic material is also used in auto parts. Such as: car bumper, power battery shell, etc. In addition, it is also used in the insulation layer of household appliances refrigerators, vegetable and fruit packaging boxes, clothing storage boxes, etc.

 

The medical and health industry has an increasing demand for blister packaging

With the development of the market in recent years, the medical and health industry has an increasing demand for blister packaging, which is good news for blister processing factories.

The blister packaging market size is estimated to grow from USD 18.65 billion in 2016 to USD 28.38 billion in 2022 at an estimated CAGR of 7.2%. The blister packaging market is expected to grow at a high rate owing to factors such as growing middle-class population, increasing demand in the healthcare industry, and popularity of convenient packaging.
In terms of value, the plastic film segment accounts for the largest market share by material and is expected to grow at the highest CAGR during the forecast period. This growth is due to its use in almost all types of packaging as it provides good product visibility and provides safe and attractive packaging. Plastic is also used as a raw material for making blister packaging because it is durable, clean, lightweight, transparent and cost-effective.

In the usage segment, the pharmaceutical industry is expected to grow at the highest rate due to high demand for pharmaceutical packaging while it provides durability and product protection and safety features. Blister packaging for health care products reduces the possibility of product contamination. It also protects healthcare products from moisture, gases, light and temperature.
In 2016, North America held the highest share of the total blister packaging market in terms of value, followed by Asia Pacific and Europe, as manufacturers focused on developing low-cost blister packaging. However, as the blister packaging market in developed countries matures, the US and Canadian markets are expected to grow the fastest between 2016 and 2022. Asia Pacific is expected to grow the fastest over the forecast period. This is attributed to the large customer base of FMCG products and consumer durables owing to the growing population of the countries in the region; thus, this is expected to instead drive the growth of the blister packaging market.
