Biodegradable Composite Packaging Factory

What is the difference between biodegradable composite packaging and general biodegradable packaging?

Biodegradable packaging are usually made of a single type of polymer (such as PLA, PHA, etc.). The main characteristic of this type of material is that it can be degraded into harmless natural components such as water, carbon dioxide and biomass under certain conditions.

Biodegradable composite packaging are made by combining biodegradable polymers with other materials (such as natural fibers, mineral fillers or other polymers). Through this combination, composites are able to improve strength, toughness, heat resistance and other mechanical properties while maintaining biodegradable properties. Composites can be designed to provide better performance and functionality for specific applications. Biodegradable composites are generally more advantageous in performance and are suitable for a wider range of application scenarios, but they also require more complex production processes and higher costs.

Should my business use biodegradable composite packaging, or will general biodegradable packaging suffice?

Applications of general biodegradable materials

Shopping bags: Shopping bags made of polylactic acid (PLA) are suitable for short-term use and can be degraded under composting conditions.

Food packaging: PLA film is used for food packaging, which can effectively isolate oxygen and extend the shelf life of food.

Disposable tableware: Tableware made of biodegradable materials facilitates take-out and fast food services in the catering industry.

Agricultural film: Biodegradable composite film is used to cover the soil, help retain moisture, and eventually degrade without generating waste.

Applications of biodegradable composites

Reinforced bags: Biodegradable composite bags made of PLA composited with natural fibers (such as corn fiber or wood fiber) to provide better strength and tear resistance.

Food packaging film: films made of biodegradable polymers and mineral fillers, with excellent oxygen barrier and mechanical strength, are suitable for packaging perishable foods.

How to choose?

The choice of using biodegradable composite packaging or general biodegradable packaging depends on your specific needs. If your films and bags require higher strength, tear resistance, or heat resistance, composites may be a better choice because they provide superior mechanical properties. At the same time, the design of composites can be optimized for different use scenarios.If your needs are relatively simple and you are mainly concerned about the degradability of the material, general biodegradable materials may be sufficient. Such materials are generally more economical and suitable for low-strength applications. Considering your product function, cost, and environmental goals before making a decision will be more beneficial to the development of your business.
