PBS biodegradable packaging bag

PBS (polybutylene succinate) is a fully biodegradable polymer material, which is an aliphatic polyester synthesized by polycondensation of 1,4-butanediol and succinic acid. The material has good mechanical properties, transparency, and processability, and can be decomposed by microorganisms into carbon dioxide and water in the natural environment without polluting the environment, so it is widely used in the manufacture of single-use products such as packaging bags.

Features

1. Environmentally friendly: PBS material can be decomposed into CO2 and H2O by microorganisms in nature under specific conditions (e.g. composting conditions) without leaving any harmful substances.
2. Safety: PBS is non-toxic and harmless to the human body, and can be used in the production of food contact products.
3. Excellent physical and chemical properties: good thermal stability, oil resistance and a certain degree of barrier; in addition, also has a good flexibility and ductility.
4. Easy processing and molding: it can be processed into different forms of products through blown film, injection molding and other ways.
5. Controllable degradation rate: by adjusting the formula or adding other components to change the degradation rate to meet different applications.

Application

1. food packaging: due to its good food safety and barrier properties, PBS is very suitable for the production of various food packaging materials, such as fruit and vegetable preservation bags, ready-to-eat meal boxes, etc.
2. Agricultural mulch film: using its biodegradable properties, it can be used for agricultural mulch, reducing the environmental pollution caused by traditional plastic film.
3. express logistics packaging: with the development of e-commerce, the express delivery industry for the growing demand for environmentally friendly packaging materials, bags made of PBS is in line with this trend.
4. medical supplies: taking into account the safety and health factors, in some medical devices or pharmaceutical packaging is also beginning to try to use PBS as raw materials.
5. Daily consumer goods: In addition to the above areas, PBS can also be used in shopping bags, garbage bags and other aspects, and gradually replace the traditional non-degradable plastic products.
