What is a biodegradable film?

Biodegradable film is a type of functional film material made from biodegradable and environmentally friendly raw materials through a blown film machine. It can gradually decompose into carbon dioxide, water and other small-molecule organic substances through the action of microorganisms (bacteria, fungi, actinomycetes, etc.) in natural environments (such as soil, seawater, compost, etc.), and eventually fully integrate into the ecological environment without generating toxic or harmful substances and without causing permanent pollution.

Biodegradable bio-materials include:

1. Plant starch (such as corn and sugarcane)
2. PLA (polylactic acid: produced by fermentation of plants such as corn and sugarcane)

3. PBAT (polybutylene adipate)：PBAT exhibits excellent flexibility and is often blended with other materials to achieve a balance between hardness and toughness.

Advantages of biodegradable film:

The raw materials are naturally biodegradable: Made from renewable bio-based materials such as corn starch, PBAT (polybutylene adipate/terephthalate), and PLA (polylactic acid), these films are decomposed by microorganisms into carbon dioxide and water in the natural environment (soil and seawater), leaving no residual pollution and fully complying with the "Plastic Ban" and environmental certification standards.

The core value of biodegradable film:

Promoting the green transformation of the industrial chain. With the global push for plastic bans, the value of biodegradable film lies not only in its environmentally friendly alternative but also in driving the green transformation of the industrial chain:

For the environment:
Reducing plastic waste accumulation, eliminating microplastic pollution, and protecting soil and marine ecosystems.
For businesses:
Helping packaging, agriculture, food, and other industries comply with production regulations and mitigate the risks of the plastic ban.
For consumers:
Providing an environmentally friendly option without the added cost of recycling (e.g., composting can be done with organic waste).

Applications of Biodegradable Film:

Due to its ability to naturally degrade after use and leave no environmental residue, biodegradable film is widely used in a variety of environmentally sensitive fields, including packaging, agriculture, and healthcare. Specific application scenarios are as follows:

Daily Use Packaging

Food Packaging: Fresh food wrap, takeout container laminating film, snack packaging, bread/fruit protective film, etc.
Daily Use Packaging: Courier cushioning film, shopping bag lining film, disposable garbage bags, and cosmetic sample packaging film.
Agriculture

Agricultural mulch films: Cover crops (such as vegetables, cotton, and corn) to insulate, retain moisture, and prevent weeds. They do not require manual collection after harvest and are naturally degradable during cultivation.
Seedling/planting films: Cover seedling trays, greenhouse linings, and fruit and vegetable bagging films (such as grape and tomato bags) reduce the impact of plastic residue on soil and crops.
Other Special Applications

Aquaculture: Isolation films for aquatic seedlings and anti-seepage membranes for aquaculture ponds (degradable in water or soil after use, preventing water and sediment contamination).
Horticulture: Flower pot packaging films and protective films for flower transport. These films degrade naturally after use, reducing the burden on horticultural waste disposal.

Biodegradable Film Blowing Machine Product Description:

Degradable plastic film is produced using biodegradable materials such as PLA and PBAT as raw materials. After mixing and drying, the material is heated and melted in the extruders. The melt is extruded through a circular die head into a film bubble, which is then inflated with air. A cooling air ring rapidly cools and shapes the film, which is then flattened by a take-up roller and finally wound into a coil by a winder. The film's thickness and width are controlled throughout the entire process using customizable parameters.

Machine Advantages and Features:

Precise Temperature Control System:
Utilizing a multi-stage heating coil and intelligent temperature control module, this system achieves ±2°C temperature accuracy and monitors the molten material temperature in real time, preventing premature material degradation or inadequate plasticization due to temperature deviations.
Customized extrusion structure:
Specially designed screw groove (deepened groove, optimized compression ratio) can enhance the kneading and plasticizing ability of degradable materials, ensure stable melt pressure, and reduce defects such as crystal points and bubbles on the film surface.
Intelligent operation configuration:
Equipped with a touch screen operating system, it supports real-time display and one-click storage of production parameters (temperature, speed, thickness). It is also equipped with a variable frequency motor and waste heat recovery device, taking into account both convenient operation and energy consumption optimization.
Reduced material waste:
Precise temperature control and stable extrusion significantly increase the film forming rate, reducing the defective rate by 80% compared to ordinary equipment. Each batch of production can reduce the loss of tens of kilograms of raw materials, and long-term use can significantly reduce production costs.
Improved production efficiency:
The customized screw design enables extrusion output to be 15% to 20% higher than traditional film blowing machines, without the need for frequent shutdowns to adjust parameters. Daily production capacity can be increased by more than 20%, helping companies quickly respond to order demands.
Lower usage threshold and costs saving:
Intelligent operation allows novices to quickly get started, reducing manual training costs; waste heat recovery and variable frequency motor design make the equipment energy consumption more than 20% lower than that of ordinary film blowing machines, which can save a lot of electricity expenses in long-term use.
Guaranteeing stable product quality:
The film surface flatness meets the industry's first-class standard, and the thickness deviation is controlled within ±3%. The biodegradable film produced can stably meet the quality requirements of food packaging, agricultural planting and other scenarios, enhancing the company's product competitiveness.

Biodegradable film's environmentally friendly and practical features can help companies address concerns about environmental sustainability but limited usability. The precision and efficiency of specialized film blowing machines overcome the production bottleneck of biodegradable film. The combination of these two forms a comprehensive "materials + equipment" solution, enabling companies to achieve environmentally friendly transformation while also generating tangible economic benefits through improved production efficiency and reduced costs. This represents the optimal combination for the current green packaging market.
