Can I Purchase Fully Biodegradable Mulch Film from Leeka Biodegradables?

The answer is absolutely yes—provided you don’t need a very small quantity. Ordering too little would increase production costs, leading to higher sales prices, which Leeka Biodegradables wishes to avoid. After all, if the product becomes too expensive for your customers to buy, purchasing it would lose its value.

Fully biodegradable mulch film is a sunrise industry, especially vital for organic and green farming. Traditional mulch films release microplastics, whose harmful substances may be absorbed by crops and enter the human food chain. In contrast, fully biodegradable mulch film effectively avoids this drawback—it gradually breaks down into water and CO₂ during the crop growth cycle, eliminating the need for secondary manual removal from soil and plants.

Leeka Biodegradables can provide bulk customization of fully biodegradable mulch film for large-scale farmers and importers in major agricultural countries. Large-volume orders significantly reduce production costs, making the unit price almost negligible.

Are Disposable Paper Cups Fully Biodegradable?

Since 2021, with the strengthening of plastic bans, demand for alternatives like paper cups has surged significantly. Starting January 1, 2025, China’s upgraded plastic ban will fully prohibit single-use plastic straws and cutlery, making pulp-based products—including paper cups and tableware—common replacements. However, disposable paper cups are not pure paper products. Since paper easily absorbs liquids, manufacturers coat the interior with a waterproof polyethylene (PE) film. When hot liquids are poured into these cups, high temperatures accelerate PE degradation, releasing microplastic particles into the beverage. Research suggests that consuming three consecutive cups of hot liquid from such cups may elevate risks to metabolic and reproductive health. While microplastics have been detected in human respiratory and digestive systems, their precise health impacts require further clinical validation.

Environmental Harm of Disposable Paper Cups

1. Recycling Challenges

The polyethylene coating complicates recycling, as separating the plastic film from paper fibers is inefficient. Most PE-laminated cups end up incinerated or landfilled, negating their recyclability.

2. Microplastic Pollution

When burned or buried, the PE film sheds microplastics that infiltrate soil and water, endangering ecosystems and human health.

3. Resource Depletion

China discards ~10 billion paper cups annually, with production consuming vast water resources and timber. Globally, 264 billion cups were manufactured in 2020—equivalent to 35 cups per person—highlighting unsustainable resource use and pollution from manufacturing emissions.

4. Regulatory Responses

Shanghai's 2025 plastic ban explicitly prohibits PE-coated paper cups, imposing fines up to 100,000 RMB for violations, targeting "greenwashed" non-sustainable products.

While marketed as eco-friendly, standard paper cups perpetuate microplastic pollution and waste. Transitioning to certified biodegradable materials is critical for genuine sustainability.Innovative materials like PLA (polylactic acid) and PBAT now offer truly compostable cups, eliminating microplastic pollution and aligning with circular economy principles. These plant-based polymers decompose safely under industrial composting conditions, resolving the environmental legacy of conventional paper cups.

What Are Microplastics? Their Potential Harm to Human Health

Microplastics refer to plastic fragments and particles smaller than 5 millimeters in diameter. In reality, their size ranges from micrometers to millimeters, forming heterogeneous mixtures of irregularly shaped plastic particles—often indistinguishable to the naked eye and colloquially termed "the PM2.5 of the sea." Compared to conventional "white pollution" plastics, microplastics pose heightened environmental risks due to their minuscule size, which intensifies their ecological impact. Globally, emerging contaminants of concern fall into four major categories: persistent organic pollutants (POPs), endocrine-disrupting chemicals (EDCs), antibiotics, and microplastics. Once released into the environment, these are classified as emerging pollutants.

Primary Sources of Microplastics:

1. Single-use plastic bags: When discarded, they take decades to degrade, fragmenting into microplastic particles that infiltrate oceans and ecosystems.
2. Disposable utensils: Takeout containers, paper cups, and similar items release copious microplastics when exposed to heat or friction, some entering the food chain.
3. Wear and tear of other plastic products.

Microplastics enter the human body via ingestion, inhalation, and other pathways, potentially triggering inflammatory responses, organ damage, endocrine disruption, and long-term risks to immune and reproductive systems. While research is ongoing, minimizing plastic exposure remains key to mitigating harm.

Potential Health Risks of Microplastics

1. Physical Damage and Inflammation

Microplastics may mechanically irritate digestive or respiratory tissues due to their sharp edges or microscopic size, provoking localized inflammation. Chronic intestinal exposure, for instance, could compromise the gut barrier, elevating permeability to toxins and potentially linking to conditions like irritable bowel syndrome (IBS).

2. Chemical Toxicity

Plastics often contain additives like phthalates (plasticizers) and flame retardants, which may leach from microplastics and disrupt endocrine function. Some compounds exhibit estrogen-mimicking effects, threatening reproductive health and child development. Moreover, microplastics readily adsorb environmental pollutants (e.g., heavy metals, polycyclic aromatic hydrocarbons), amplifying toxic co-exposure.

3. Organ and Cellular Accumulation

Animal studies reveal microplastics crossing the blood-brain and placental barriers, accumulating in organs like the liver and kidneys, and inducing oxidative stress and cellular dysfunction. Human studies have detected microplastics in blood, placenta, and even breast milk—though long-term health implications remain unclear, chronic accumulation may elevate disease risks.

4. Immune System Disruption

Microplastics can be flagged as foreign bodies, triggering excessive immune responses that fuel chronic inflammation or autoimmune disorders. Nanoparticles might further disrupt immune cell signaling, impairing pathogen defense.

5. Other Potential Risks

Some research hypothesizes links between microplastics and neurodegenerative diseases (e.g., Alzheimer’s) via neuroinflammation, while other studies suggest they may alter gut microbiota, indirectly affecting metabolism and immunity.

A Brief Discussion on PLA Used in Biodegradable PLA Bags

 Polylactic acid (PLA) fiber is synthesized from agricultural products rich in starch, such as corn, wheat, and sugar beets. Through fermentation, lactic acid is produced, which is then polymerized and melt-spun into fibers. PLA fiber is a synthetic material derived from renewable, easily cultivable crops, and its waste products are fully biodegradable in nature. Under microbial action in soil or seawater, PLA breaks down into carbon dioxide and water. When incinerated, it does not emit toxic fumes or cause pollution, making it an eco-friendly, sustainable fiber. Fabrics made from PLA exhibit excellent drape, a soft hand feel, UV resistance, low flammability, and superior processability, making them suitable for fashion, casualwear, sports apparel, hygiene products, and more—demonstrating broad application potential.

Since PLA fiber is derived from lactic acid obtained from corn starch, it is also called "corn fiber." Alternatively, lactic acid can be produced via glucose fermentation from sugar beets or grains to reduce production costs for lactic acid polymers. High-molecular-weight PLA can be synthesized through chemical polymerization of lactide (lactic acid cyclic dimer) or direct polymerization of lactic acid. Products made from PLA exhibit excellent biocompatibility, bioabsorbability, antibacterial properties, and flame retardancy. Among biodegradable thermoplastic polymers, PLA boasts the highest heat resistance.

PLA fibers share physical properties similar to PET fibers (polyester), including high crystallinity and transparency. Due to their high crystallinity and orientation, PLA fibers offer exceptional heat resistance and strength without requiring specialized equipment or processing techniques—standard spinning methods suffice.

Raw materials for PLA production, such as sugar beets and corn, are abundant and renewable through cultivation. Unlike petroleum or wood-based materials, PLA production helps conserve finite fossil fuel and forest resources. The primary feedstock for PLA is lactic acid (α-hydroxypropionic acid or 2-hydroxypropionic acid). As lactic acid contains an asymmetric carbon atom, it exists in two enantiomeric forms: D-lactic acid (dextrorotatory) and L-lactic acid (levorotatory). An equal mixture of both yields optically inactive DL-lactic acid. Fiber-grade PLA typically uses L-lactic acid as the monomer.

PLA fibers are fully biodegradable, decomposing naturally into CO₂ and H₂O after disposal. These compounds can then be converted back into starch—the source material for lactic acid—via photosynthesis. When buried with organic waste, PLA fibers decompose completely within months, breaking down into CO₂ and H₂O.

Among all biodegradable polymers, PLA possesses the highest melting point, high crystallinity, and excellent transparency, making it ideal for fibers, films, and molded products. Its physical properties closely resemble PET (polyester) and PA (nylon) fibers, while its dyeability surpasses PET.

PLA is a critical component in fully biodegradable materials. If you require PLA pellets or for finished product formulations, LEEKA biodegradables is your most professional and trusted source.

The Staggering Global Use of Garbage Bags & Why We Need Biodegradable Alternatives

Every day, millions of tons of waste are generated worldwide, and most of it ends up in plastic garbage bags. These bags, though convenient, contribute significantly to pollution, landfills, and ocean contamination. But there's a sustainable alternative: biodegradable garbage bags. Let's explore the scale of the problem and why switching to eco-friendly disposal methods is urgent.

How Many Garbage Bags Are Used Every Day?

Globally, over 1 trillion plastic bags are used each year, with millions discarded daily. Here’s a breakdown:

• - The average person uses 1-2 plastic garbage bags daily.
• - In the U.S. alone, an estimated 100 billion plastic garbage bags are used each year.
• - Many end up in landfills (where they take 500+ years to decompose) or the ocean (killing marine life).

The Environmental Impact of Traditional Garbage Bags

Plastic pollution is worsening:

Non-biodegradable – Most garbage bags are made from polyethylene, which does not fully break down.

Landfill overflow – Plastic bags clog landfills, releasing methane (a potent greenhouse gas).

Microplastic contamination – Over time, plastics break into tiny toxic particles, entering soil and water, which is the worst problem. This situation is same like when we breath air, dust are inside it; when we drink water, microplastics are in it. Do you want to drink pure water or water full of impurities?

Ocean threat – Millions of marine animals die annually from ingesting or getting tangled in plastic waste.

The Solution? Biodegradable Garbage Bags

Biodegradable garbage bags are made from plant-based materials (e.g., cornstarch, PLA) that decompose within months instead of centuries.

Why We Need to Switch NOW:

• Reduced pollution– They break down into natural elements without microplastics.
• Lower carbon footprint – Made from renewable sources (not fossil fuels).
• Compostable – Some can even be turned into fertilizer.
• Safe for wildlife – Won’t harm animals if accidentally consumed.

What Can You Do?

• Replace plastic garbage bags with biodegradable/compostable alternatives.
• Support policies that ban single-use plastics.
• Spread awareness – The more people know, the faster change happens!

Final Thought

The world dumps millions of plastic garbage bags daily, poisoning ecosystems for centuries. Switching to biodegradable garbage bags is not just an option—it’s a necessity for a cleaner, healthier planet.

Make the change today. Future generations depend on it.
