PET blister sheet: transparent protection, fresh presentation

PET blister sheet, a transparent packaging material popular in the Middle East market with its excellent performance and environmental protection advantages, is quietly changing the food packaging industry. It is like an invisible protective film that firmly locks fresh fruits and vegetables and protects your products.

PET blister sheet: born in technology, achieved in environmental protection

PET, full name polyethylene terephthalate, is a high molecular polymer material. The birth of PET blister sheets is inseparable from the inventions and creations of scientists in the 1930s. After continuous improvement and innovation, PET material has gradually become the darling of the packaging industry with its excellent performance and environmental protection advantages.

The production process of PET blister sheets mainly includes the following steps:

Raw material preparation: PET particles are processed through drying, mixing and other processes before use.

Extrusion molding: The PET raw material is heated and melted, and then shaped into a film-like PET sheet through an extruder.

Blister molding: Place the PET sheet on the blister mold, use vacuum negative pressure to make the sheet adhere to the shape of the mold, and after cooling and shaping, the required blister product can be obtained.

The reason why PET blister sheets are so popular in the Middle East market is due to its incomparable advantages:

• High transparency: PET material itself has extremely high transparency, which can clearly display the appearance of the product and attract consumers’ attention.
• Excellent barrier properties: PET blister sheets have good barrier properties and can effectively block oxygen, water vapor, etc., extending the shelf life of food.
• Good heat resistance: PET blister sheet has good heat resistance and can be used for microwave heating, which is convenient and fast.
• High strength: PET blister sheet has high strength and stiffness, can withstand a certain amount of pressure and impact, and protects products from damage.
• Recyclable: PET material is recyclable and meets environmental protection requirements.

History and heritage: from laboratory to table

The invention of PET material dates back to the 1930s. At that time, scientists were looking for a new type of synthetic fiber material and finally successfully synthesized PET. Initially, PET was mainly used in the textile field to produce polyester and other chemical fiber products. With the advancement of science and technology, PET materials are gradually used in the packaging field.

In the 1950s, with the birth of blister molding technology, PET blister sheets began to be mass-produced. PET blister sheets have quickly gained a foothold in the packaging market with their excellent performance and environmental protection advantages. Today, PET blister sheets have become one of the indispensable materials in the food packaging industry and are widely used in the packaging of fruits, vegetables, meat, poultry and other foods.

Broad prospects: leading new packaging trends

With the improvement of people’s living standards and the enhancement of environmental awareness, consumers have put forward higher requirements for food packaging. With its excellent performance and environmental protection advantages, PET blister sheets conform to this trend and become the inevitable choice for the future development of the food packaging industry.

The application fields of PET blister sheets will continue to expand, not only limited to food packaging, but also used in the packaging of electronic products, stationery, toys and other products.

PET blister sheet, a transparent guardian, provides a reliable solution for food preservation and quality preservation. With the advancement of science and technology and the expansion of application fields, PET blister sheets will bring more convenience and environmental protection experience to our lives.
