Description

What are biodegradable plastic bags?

They are known for their high structural flexibility, excellent mechanical strength, controlled water absorption and good organic breakdown abilities. The bags, which do not contain toxic residues or microplastics when broken down, decompose micro organically, unlike traditional fossil fuel-based plastics which can stay in landfill for decades.

In many industrial and commercial applications, Biodegradable Plastic bags are available and used to deliver lightweight packaging that is extremely resistant to puncture. These are also cost efficient. These bags perform extremely well in municipal environments. They are compatible with organic kitchen scraps and wet food waste. Biodegradable bags are superior to synthetic bags because they offer a better eco-balance, excellent chemical passivity and are ideal for corporate retail outlets, sustainable campuses and environmentally conscious shipping.

There are various types of biodegradable plastic bags that are available

Virgin Bio-Based Bags

Composed of 100% pure cornstarch or PLA composite resins, providing a best possible material consistency and high tear resistance.

Retail T-Shirt Carrier Bags

These bags feature comfortable and sturdy vest or punch-out handles. They are also designed with gusseted side panels to securely hold retail consumer products at checkouts.

Roll-Form perforated liners

On request, these rolls are available as coreless continuous rolls with clean tear lines. They can be easily dispensed in commercial kitchens or corporate offices.

Color coded Organic Segregation Bags

These biodegradable containers come in different shades like light green and natural tan.

Size & Volumetric Capacity Frameworks

We can adapt our factories to your specific packaging configurations, waste disposal systems and dimensional requirements.

• Pre-cut flat industrial liners in standard 4x8 dimensions. Ideal for lining bulk component shipping containers.
• Custom-cut Retail Bags: Small and medium sizes to suit custom pharmacy pouches, boutique shopping needs.
• Industrial Fabrication Liners: Medium-thick custom bags for cafeteria bins with high volume and food scraps.
• Thick Heavy Duty Storage Sacks : These sacks are extra-thick and high-gauge, designed to hold heavier soils, composts, or agricultural inputs that have been wet.

Manufacturing Process Overview

We at Singhal Industries Private Limited manufacture our biodegradable bags with strict quality parameters under Multi-layer co-extrusion blown film technology.

• Step 1: Raw Compounding Selection: Batch purity, performance indicators, bio-polymer, plant-starch composites and certified bio-polymer are selected.
• Step 2 – Blown film extrusion: Using the circular die systems, the compounded resin pellets are melted at carefully controlled temperatures and extruded vertically into large plastic bubbles.
• Step 3: Calibrating the tubes and forming the sheets: The rising bubble is stabilized by air cooling rings to achieve a precise uniformity of micron film thickness.
• Step 4. Cooling and Corona Calibration: Chilled rollers move the film through for maximum surface treatment. This sets it up for clean ink print.
• Step 5: Eco-Ink printing and testing : Printed with non-toxic inks. The thickness, elongation and the strength of the seam seal for each production batch are then checked for accuracy.
• Step 6: Die-Cutting & Packing & Dispatching: Computer-operated die cutting is followed by bottom heat sealing of sheets, after which the bags are packed and shipped to overseas markets.

FAQs (Frequently Asked Questions)

Q1: How are biodegradable plastic bags used?

The use of biodegradable plastic bags is widespread in commercial retail checkout carriers, restaurant kitchen scrap collection, corporate trash bin liners and packaging for consumer products.

Q2: Will these bio-based bags weaken or melt when they are exposed to hot items?

Our bags are heat resistant up to 55degC and remain structurally stable in standard industrial packaging or ambient warehouse conditions.

Q3: Is your biodegradable bag fully chemical resistant

They are highly reliable in terms of waste collection because they have excellent resistance to kitchen grease, natural organic acids, weak household alkalis and moisture.

Q4: Can these sheets be heat sealed effectively on automated packaging machines?

This will enable them to produce clean and airtight bottom welds on high-speed automatic packaging machines.

Q5: Is it possible to produce waterproof biodegradable bags?

Yes.

Q6: What is the principal difference between a PLA-biodegradable bag, and an LDPE-garbage bag?

PLA biodegradable bags are plant-based and sustainable. Such bags break down into compost. LDPE bags are based on petroleum. It means that these bags do not decompose.

Q7: Is it possible for us to place an order for customized dimensions and specific print configurations of the brands for our product use?

Singhal Industries Private Limited provides such a possibility. You may select the custom roll sizes and thicknesses along with the high-contrast logos printed with eco-friendly inks.

Q8: Do these bags decompose after being stored in the storage facility for a long time?

No.

Q9: In which industries are biodegradable plastic bags used?

Biodegradable bags can be successfully applied in the fields of retail e-commerce packaging and facilities management. They are also used in agricultural cultivation, commercial accommodation, and consumer products manufacturing.

Q10: What thickness of bag would I select for my facility?

It depends on the weight of your product, risk factors during transportation and environment-friendly goals. Groceries would require bags of 15 microns. Heavy duty bags of 60-80 microns would be suitable for industry waste.

Q11: Can exposure to air humidity ruin the bag completely?

No. Our bio-fibers, though intended to be environment-friendly, can resist moisture. However, these bags will break only in case of disposal in a composting site.

Q12: Can recycled material be used in manufacturing packaging for fresh food items?

For safe use, we advise you to use our virgin bio-based 100% pure bags for packing organic products.

Q13: Can these bags resist sunlight during long shipping processes?

It have been made stable in order to avoid breaking during transportation. Nevertheless, they need to be kept away from sunlight when being stored.

Q14: In what ways will the lightness of these bags help cut down on transportation costs?

The bags mentioned above have been designed to achieve optimum density and hence add little weight to bulk cargo. This helps in minimizing your deadweight costs and cuts down your freight costs.

Q15: In what manner should one go about making a bulk purchase?

Procurement managers can contact the export trading division directly and give required size profile and thickness ranges.
