What is the Difference Between Biodegradable Plastic Bags and Recycled Plastic Bags?

Biodegradable plastic bags and recycled plastic bags are produce by different types blown film machines.

What are the biodegradable plastic bags?

Currently, most biodegradable materials on the market are made of PBAT +PLA materials. PBAT has strong film-forming properties due to its good ductility and tensile strength. It is easy to blown film and is widely used in packaging and agriculture.

Recycled plastic bags refer to bags produced from plastic raw materials obtained after processing waste plastics through physical or chemical methods such as pretreatment, melt granulation, modification, etc. The raw materials include primary recycled materials, secondary recycled materials, and third-level recycled materials. The advantage of recycled plastic bags is that they are cheaper than new materials and degradable plastic bags, saving resource waste and reducing environmental pollution.

What are the advantages of biodegradable plastic bags?

Biodegradable plastic bags have their advantages in performance, practicality, degradability and safety. In terms of performance, biodegradable plastic bags can reach or exceed the performance of traditional plastics in some specific fields; in terms of practicality, biodegradable plastic bags have similar application performance and hygienic performance to similar traditional plastics. In terms of degradability, After use, biodegradable plastic bags can quickly complete the peak decomposition in the natural environment (specific microorganisms, temperature, and humidity) and become fragments or non-toxic gases that are easily utilized by the environment, reducing the impact on the environment; in terms of safety, The substances produced or remaining during the decomposition process of biodegradable plastic bags are harmless to the environment and will not affect the survival of humans and other organisms. 

In applications such as packaging and agricultural films who are difficult to recycle and separate and have low performance requirements, high impurity content requirements. So the biodegradable plastic bags have more advantages as alternatives.

How to choose a suitable machine that produces biodegradable bags?

1. Machine type

Choose the appropriate machine type according to the specific needs of biodegradable bags. Common biodegradable bag production machines include film blowing machines, bag making machines, embossing machines, etc. Determine the type of machine required based on the production scale and process requirements.

2. Production capacity

Select the production capacity of the machine based on the expected output requirements. Production capacity is usually measured in terms of production quantities per minute or hour. Make sure the machine's production capacity can meet your production needs.

3. Technical parameters

Understand the technical parameters of the machine, including maximum film width, film thickness range, speed control range, etc. These parameters determine the machine's production capacity and the types of films it can adapt to.

4. Degree of automation

Consider the degree of automation of the machine. Highly automated machines can improve production efficiency and quality stability, and reduce labor costs and operational risks. Choose the appropriate degree of automation based on actual needs.

5. Quality and reliability

Choose machines with high brand awareness and reliable quality. Understand the quality and reliability of the machine by reading customer reviews, referring to industry reputation, and consulting professionals.

6. After-sales service

Understand the supplier's after-sales service support, including maintenance, parts supply, etc. Ensure timely technical support and service guarantee during use.

7. Cost and return on investment

Consider the price of the machine, operating costs and expected return on investment. Choose a machine that fits your budget and offers good value for money.
