In the vanguard of environmental consciousness, the narrative around packaging has dramatically shifted. Sustainability, once a mere trend, has become an imperative, with biodegradable stretch films emerging as a beacon of hope. This comprehensive discourse ventures into the realm of biodegradable stretch film manufacturers, unraveling the intricate tapestry of technology, innovation, and the challenges that sculpt this burgeoning domain.
The Urgent Shift Toward Eco-Friendly Packaging Solutions
An eco-conscious zeitgeist, propelled by informed consumer bases and stringent regulatory landscapes, demands sustainable packaging solutions. Biodegradable stretch films stand at the forefront of this revolution, offering a greener alternative to the conventional plastic menace.
Defining Biodegradable Stretch Film: A Sustainable Alternative
Biodegradable stretch film distinguishes itself through its inherent capacity to decompose naturally, attributed to the biodegradable materials constituting its makeup. This section delves into the essence of what sets biodegradable stretch films apart, spotlighting their environmental benevolence.
The Green Chemistry Behind Biodegradable Stretch Films
Key Ingredients: From Plants to Polymers
The cornerstone of biodegradable stretch film innovation lies in the utilization of renewable resources. Plant-based polymers, pivotal in this green chemistry, undergo natural decomposition, reducing environmental impact and fostering a cycle of sustainability.
Key Materials and Processes: At the heart of these innovations are materials such as PLA (Polylactic Acid), PHA (Polyhydroxyalkanoates), and PBS (Polybutylene Succinate), derived from renewable resources like corn starch, sugarcane, and other biomass. The manufacturing processes have been refined to enhance the mechanical properties of these films, ensuring they meet the rigorous demands of various packaging needs while being compostable.
The mainstream degradable stretch film biodegradable plastic film roll on the market is PBAT+PLA. Sinyar launched the most suitable solution for the biodegradation of stretch film biodegradable plastic wrap-Chitosan Degradable Stretch Film.
Synthetic degradable plastics
PLA； PBS； PHA； PBAT
Note: Distinguish degradable、 biodegradable and copostable
Many degradable shretch film merchants will confuse these three concepts, although the keyword
is written as “biodegradable”, what is it exactly, is not easy to say.
Note: Distinguish degradable 、biodegradable and compostable
Degradable plastics Include plastics that can be degraded by physical and biological factors (light, heat, or microorganisms). Most of the products on the market are just ordinary plastics (such as PE) with biodegradable fillings.
There are many oxygen-degradable plastic stretch films on the market, which are low in price but not good for the environment and health – such plastics will only disintegrate into plastic fragments, and will not decompose and disappear in a certain time.
Biodegradable plastic: refers to a plastic that degrades under conditions such as soil in nature, and specific conditions such as composting conditions, caused by the action of microorganisms present in nature， and eventually completely degraded into carbon dioxide or/and methane, mineralized inorganic salts and water.
| Material | Comparison of degradation modes and rate |
| PLA | Industrial composting conditions (above 5O℃, aerobic flora) : the degradation rate of 84% in 58 days Anaerobic composting conditions (58℃, 60% humidity) : 30 days degradation rate 60% |
| PBAT | Moisture sufficient soil conditions: 5 months can be completely degraded Simulated seawater conditions (25℃ ±3℃): about 30-60 days can be completely degraded |
| Starch-based plastic | Anaerobic composting conditions (58℃): degradation rate of 85% in 90 days In soil environment (35℃): 60 days degradation rate of 35% |
Different from PBAT biodegradable stretch film, chitosan biodegradable stretch film can achieve complete degradation in the natural environment, without manual intervention. That is to say, it only needs sunlight, air, humidity, microorganisms and other elements of nature, without any artificial intervention and composting, it can achieve full biodegradation.
Degradation principle 1: natural transformation (pre-degradation)
Degradation Principle 2: Biodegradation (Post-Degradation)
1. Biodegradation auxiliaries will attract more microorganisms to gather and colonize
2. After the fusion of degradation auxiliaries and PE, the natural transformation increases the specific surface area of the material, making degradation efficiency higher.
3. The combination of chitosan and other biodegradation auxiliaries will stimulate microbial reproduction and secretion of degradation enzymes to achieve complete degradation in the natural environment.
Under natural conditions: In about two months, the molecular weight of PE decreased by about 60% to 80%.
• The substrate is polyolefin, and its toughness, elasticity and tensile strength are similar to those of ordinary stretch film
• It has a nourishing effect on the soil and makes it more fertile
• Degradation of more than 90% in 180-day
Remarkably, it only degrades in soil. So it can effectively extend the storage time.
| PBAT+PLA | Chitosan |
| The stretch film of PBAT+PLA has a short life cycle and a degradation period of 3-5 months. In the process of using the product, it is easy to age and crack. If the PBAT+PLA stretch film is used to wrap the items, there may be a danger of the items being dumped. | The life cycle of chitosan stretch film is 24 months, and the degradation period is 12-24 months, which is more suitable for the needs of stretch film. Its physical properties are better than PBAT. The functionality of the stretch film does not change during 24 months of use. |
| PBAT+PLA stretch film is compostable degradable plastic, which needs to be degraded under certain composting conditions, and the implementation conditions are relatively high. Full degradation cannot be achieved in the natural environment. | PBAT+PLA stretch film is compostable degradable plastic, which needs to be degraded under certain composting conditions. Full biodegradation can also be achieved under natural conditions. |
| The cost of PBAT+PLA stretch film is high, which is not recognized by many countries | The cost of chitin stretch film is controllable. |
The Manufacturing Process: Harmonizing Nature with Technology
The fusion of natural ingredients and avant-garde technology births biodegradable stretch films that are not only eco-friendly but also efficacious in application. This synthesis underscores a commitment to environmental stewardship without compromising on packaging integrity.
Biodegradability vs. Compostability: Clarifying the Concepts
A critical examination of biodegradability versus compostability elucidates the nuanced differences between these terms, providing clarity on their relevance to stretch films and their environmental implications.
Compostable plastics: To better define degradable, relevant institutions in Western countries have introduced compostable standards (such as the ASTM6400 standard in the United States). As long as the product meets the standard and passes the institutional test, a certificate can be obtained to prove that the product is “compostable”, which is divided into household composting and industrial composting according to different composting conditions. That is to say, compostable plastics are to meet certain composting conditions.
Environmental Impact and Benefits
The environmental implications of switching to biodegradable stretch films are profound. Traditional plastic films, notorious for their persistent nature, contribute significantly to landfills and ocean pollution. Biodegradable options, however, decompose into water, carbon dioxide, and biomass within a few months to a couple of years, depending on the composting conditions.
Regulatory Landscape: Governments worldwide are implementing policies to curb plastic waste, with bans on single-use plastics and incentives for sustainable alternatives. These regulations are propelling the growth of the biodegradable stretch film market, as manufacturers rush to comply and capitalize on the emerging opportunities.
Reduced Carbon Footprint: The production of biodegradable stretch films typically consumes less energy and emits lower volumes of greenhouse gases compared to conventional plastics. This transition aids in the global efforts to combat climate change by reducing the carbon footprint associated with packaging.
Promoting Circular Economy: By embracing biodegradable stretch films, manufacturers are contributing to a circular economy. This approach emphasizes the reuse and recycling of resources, ensuring that products and materials are utilized efficiently and sustainably.
