Detailed Description of Biodegradable Packaging Bags
The materials used in biodegradable packaging bags are their core feature. Polylactic acid (PLA) is polymerized from lactic acid extracted by fermentation of plants such as corn and sugarcane. It not only has good mechanical properties and transparency but also decomposes rapidly under composting conditions. Polyhydroxyalkanoates (PHA) are natural polyesters synthesized by microorganisms, possessing excellent flexibility and biocompatibility.
In terms of bag types, flat bags have a simple structure, suitable for packaging small items; handbags have handles for easy carrying of heavy objects; resealable bags can be reused due to their sealing design, convenient for storing unused items.
In addition, the printing of biodegradable packaging bags usually uses environmentally friendly inks to ensure the overall environmental attributes of the packaging. At the same time, these bags can be customized according to different product needs, such as adding moisture-proof layers or anti-static treatment.
For example, a biodegradable packaging bag for organic food might use PLA material, be a resealable bag, and have organic certification marks and environmentally friendly slogans printed on it, conveying a green concept.

What is a Biodegradable Packaging Bag Product?
Biodegradable packaging bags are a series of bags made from biodegradable materials, used to contain and protect various items. They are a concrete manifestation of environmentally friendly concepts in the packaging field.
It is a concrete manifestation of environmentally friendly concepts in the packaging field.
  
Why is it called a Biodegradable Packaging Bag?
Because the materials used in its manufacture can gradually decompose in the natural environment or under specific conditions through the action of microorganisms, returning to nature, it is called a biodegradable packaging bag.
  
What types of bags are there for biodegradable packaging bags?
Common types of biodegradable packaging bags include:
Flat bags: The opening is flat, easy to fill and seal.
Handbags: With a handle, convenient for carrying heavy objects.
Resealable bags: Has a resealable opening, can be opened and closed multiple times.

Material Parameters and Characteristics of Biodegradable Packaging Bags
Characteristics:
Environmentally friendly and biodegradable, reducing long-term environmental pollution.
Renewable material sources, reducing reliance on fossil resources.
Possesses a certain mechanical strength and barrier performance to meet packaging needs.
Material Parameters:
The tensile strength of PLA is usually between 50 and 70 MPa, and the degradation time is generally between a few months and two years.
The elongation at break of PHA can reach more than 300%, and the specific degradation rate is affected by environmental factors.
Biodegradable Packaging Bag Processing Flow
Material Preparation: Processing biodegradable materials such as PLA and PHA into granular form.
Extrusion Molding: Heating and melting the granules through an extruder and extruding them into a film.
Printing (if needed): Using environmentally friendly inks for printing patterns and text.
Bag Making: Cutting, heat-sealing, or sewing the film into various bag types.
