Our Wholesale Customization Process
Raw material type: mainly biodegradable materials are used, including:
Polylactic acid (PLA): extracted from corn, sugar cane, etc., giving the bag strength and transparency.
Polybutylene succinate (PBAT): provides flexibility and durability.
Corn starch: enhances compostability and cost-effectiveness. such as plasticizers and antioxidants to ensure processing performance.
- The pellets are fed into the film blowing machine and heated to 160-200°C to form a molten state.
- Extruded through a ring die, compressed air is blown into a film tube (thickness is usually 15-50 microns, depending on product requirements).
- The film tube is shaped by a cooling air ring and stretched to a specified width by a traction roller.
- Flatten the film tube and roll it into a double-layer film roll, and check whether there are bubbles, damage or uneven thickness on the film surface.
Purpose: Customize brand logos, patterns or environmental logos (such as “Compostable” logo) for customers.
- Choose environmentally friendly water-based inks (compactable) to avoid heavy metals in traditional inks.
- Use flexographic or gravure printing presses to print the design onto the film surface.
- Dry after printing to ensure that the ink is firmly attached.
- Check the printing quality to ensure that the pattern is clear and not offset, meeting customer requirements.
Purpose: Process the film into bags of specific shapes and sizes.
Feed the film roll into the bag making machine and set the parameters according to the product type (such as vest bags, flat bags, roll bags).
Cutting: Cut the film into specified sizes by heat sealing knife or ultrasonic cutting.
Sealing: Use heat sealing technology to form the bottom or side seals of the bag to ensure sealing and load-bearing capacity.
Special processing (on demand):
Perforation: Easy to tear the roll bag.
Handle design: Such as the handle of dog poop bags.
Folding: Such as the side fold of kitchen waste bags.
Rolling or stacking bags: Roll the finished bags (such as roll bags) or stack them (such as flat bags).
Purpose: Ensure that the product meets environmental certification and customer requirements.
Physical performance testing:
Tensile strength and elongation at break (to ensure the durability of the bag).
Load-bearing test (for example, a 35L kitchen waste bag can bear more than 10kg).
Sealing test (to prevent leakage).
Environmental performance test:
Biodegradation rate (more than 90%, in compliance with AS4736).
Heavy metal content detection (to ensure non-toxicity).
Appearance inspection:
Surface flatness, no defects.
Printing accuracy (such as LOGO position).
Sampling and inspection by third-party institutions (such as SGS) to obtain certification reports.
Small batches: carton packaging, lined with compostable bags.
Large batches: pallet packaging, fixed with wrapping film.
Affix bilingual labels (English + French, in compliance with Australian regulations), including product specifications, certification marks and instructions for use.
Arrange logistics: export to Australia by sea or air, in accordance with customer customs clearance requirements.
Provide necessary documents: such as AS4736 certification, certificate of origin, packing list.
