What is biodegradable plastic?

Degradable plastics are a class of polymers whose products meet the required performance standards during their shelf life and, after use, break down under natural environmental conditions into substances that are harmless to the environment. Consequently, they are also referred to as environmentally degradable plastics. Polymer degradation refers to the process by which the macromolecular chains of a polymer are cleaved due to chemical and physical factors. When polymers are exposed to environmental conditions such as oxygen, water, radiation, chemicals, pollutants, mechanical forces, insects, and microorganisms, the resulting chain‑cleavage process is known as environmental degradation. Today, several new types of plastics are available, including photodegradable plastics, biodegradable plastics, fully degradable plastics that combine photodegradation, oxidation, and biodegradation, carbon‑dioxide‑based biodegradable plastics, and thermoplastic starch‑based degradable plastics. Biodegradable plastics can be used not only to manufacture various sports goods—such as fishing lines and golf tees—but also materials for agriculture, forestry, and aquaculture, including films, moisture‑retaining materials, and seedling‑bed substrates, as well as garbage bags and hygiene products like disposable diapers. Their potential applications are even broader, extending to cosmetic containers, toothbrushes, cushioning materials, packaging, shopping bags, and single‑use gloves. If safety concerns can be adequately addressed, they could also serve as food‑contact packaging. As a novel functional polymer material, biodegradable plastics find uses in packaging for fertilizers and pesticides, as well as in product‑packaging applications. In the future, they may also find applications in non‑plastic sectors such as adhesives and printing inks. With growing public concern over “white pollution” and the implementation of plastic‑restriction policies across provinces and municipalities, how to better leverage degradable plastics will become a critical issue for the market going forward.

Material Selection for Vacuum Packaging Bags

PET primarily refers to polyethylene terephthalate (PET) and polyethylene. PET vacuum bags are colorless, transparent, and glossy. They exhibit excellent mechanical properties, with high rigidity, hardness, and toughness, as well as superior resistance to puncture, abrasion, high temperatures, chemicals, oils, and outstanding gas barrier and aroma‑retention characteristics.

BOPP film is a commonly used material for packaging bags.

Plastic films have evolved into one of China’s major plastic products, characterized by high production volumes and a wide variety of types. They are extensively used in packaging, architectural decoration, electronics and electrical appliances, as well as everyday consumer goods, with the packaging industry being the most prominent application area. In addition to traditional PE and PVC, BOPP (biaxially oriented polypropylene) and BOPET…

What are plastic products in everyday life made of?

Plastics are high‑molecular‑weight resins obtained through polymerization, starting from petroleum or natural gas that is refined and cracked into various petrochemical feedstocks. They belong to the class of polymeric materials. In the early days, coal‑tar products and calcium carbide were the primary raw materials; today, petroleum‑ and natural‑gas‑derived feedstocks such as ethylene, propylene, benzene, formaldehyde, and urea are predominantly used.

Material Structure of Composite Packaging Products

Packaging bags are used to encase various products, facilitating transportation and storage throughout the production and distribution processes. They are widely employed in both everyday life and industrial manufacturing. Based on their manufacturing processes, they are commonly categorized into plastic packaging bags and composite packaging bags. Composite packaging materials are designed to enhance key properties such as air permeability, moisture resistance, oil resistance, water resistance, and chemical resistance, while also providing protection against insects, dust, microorganisms, and odors—such as light, fragrance, and unpleasant smells. Additionally, these materials offer improved heat and cold resistance, impact resistance, superior mechanical strength, and enhanced processability, along with excellent printability and decorative appeal.

One of the commonly used materials for packaging bags is PET.

PET, or polyethylene terephthalate, is the most important member of the thermoplastic polyester family. Its English name is Polyethylene terephthalate, abbreviated as PET or PEIT (hereafter referred to as PET), and it is commonly known as polyester resin. It is a condensation polymer formed by the reaction of terephthalic acid with ethylene glycol.
