About Changzhou Green Cradleland Macromolecule Materials Co., Ltd. - Industrial Tapes/Films Supplier in China

Changzhou, China hosts Changzhou Green Cradleland Macromolecule Materials Co., Ltd., which currently lists seven active products. The company classifies its output under industrial tapes/films, medical bags, and polypropylene plastic bags. Its catalogue includes water‑soluble PVA films, nonwoven sheets, and various laundry bag formats. These items fall within the polymer film and polymer bag segments commonly traded under HS chapter 39. The supplier’s portfolio therefore spans both consumer‑grade and specialty medical‑grade polymer solutions.

The specific items are a PVA water soluble film, water soluble nonwovens, a PVA water soluble laundry bag, medical‑use water soluble laundry bags, disposable dissolvable laundry bags for hospitals, biodegradable water soluble plastic laundry bags, and a high‑quality agricultural mulch film. All products are described as water‑soluble or biodegradable, indicating a focus on environmentally responsive polymers. The agricultural mulch film is intended for seasonal crop coverage, while the medical laundry bags target infection‑control applications. The range suggests capability to produce both thin films for packaging and thicker films for field use. No additional product families are listed beyond these seven.

Product Range and Specialties of Changzhou Green Cradleland Macromolecule Materials Co., Ltd.

The catalogue presents a PVA water‑soluble film typically hydrolyzed to 85‑90 % with thicknesses from 10 µm to 30 µm and a dissolution time of 30‑120 seconds in warm water. Water‑soluble nonwovens are usually supplied at 30‑80 gsm and are engineered for rapid disintegration in aqueous environments. Laundry bags for general use and for medical settings are commonly fabricated from the same PVA base but differ in compliance: medical bags are often produced to meet FDA food‑contact or ISO 13485 standards, while biodegradable versions aim for EN 13432 certification. The agricultural mulch film is generally a polypropylene or low‑density polyethylene film, 50‑150 µm thick, UV‑stabilized, and may carry a light‑diffusion grade for crop protection. Across these categories, buyers normally request data on tensile strength (MPa), elongation at break, solubility rate, and biodegradation percentage after 90 days.

Trade and Export Information - Changzhou Green Cradleland Macromolecule Materials Co., Ltd.

China is a leading exporter of polymer films and specialty bags, supplying bulk shipments to Southeast Asian garment manufacturers, European agricultural distributors, and North American medical device firms. Buyers of water‑soluble films usually import under HS 3910 (polyethylene and polypropylene films) and HS 3920 (other plastics articles) classifications, though exact codes depend on the final polymer composition. Typical certifications requested by importers include FDA food‑contact approval for laundry bags, CE marking for medical‑grade bags, and EN 13432 for biodegradable products. Exports are frequently shipped in 20‑foot or 40‑foot containers, with pallets wrapped in moisture‑resistant film; common Incoterms are FOB Changzhou or CIF destination port. Chinese exporters of these polymers must comply with REACH registration for EU markets and may need to provide a Material Safety Data Sheet (MSDS) and third‑party test reports for solubility and tensile performance.

Sourcing from Changzhou Green Cradleland Macromolecule Materials Co., Ltd. - Buyer Guidance

When sourcing water‑soluble films or bags from this supplier, request an MSDS, a recent third‑party lab report confirming PVA hydrolysis level, thickness tolerance, and dissolution time, and, for medical bags, a certificate of compliance with ISO 13485 or FDA 510(k) clearance. Verify that biodegradable laundry bags carry EN 13432 test results showing ≥90 % degradation within 90 days in a composting environment. Samples should be inspected for uniform thickness, visual clarity, and consistent tear resistance before placing a bulk order. Confirm packaging details - typically bulk rolls for films (e.g., 1 m × 1 km) or stacked bags on moisture‑proof pallets - and agree on Incoterm (FOB or CIF) to align logistics costs.

What polymer material is used for the PVA water soluble film?

The film is produced from polyvinyl alcohol (PVA) with a hydrolysis degree of 85‑90 %, which provides rapid water solubility while maintaining film strength.

Are the medical laundry bags compliant with any international standards?

Medical‑use water soluble laundry bags are typically manufactured to meet FDA food‑contact requirements and ISO 13485 quality‑management standards for medical devices.

What is the typical thickness and dissolution rate of the water soluble nonwovens?

Nonwoven sheets are supplied at 30‑80 gsm and are designed to dissolve completely in warm water within 1‑3 minutes, depending on temperature and agitation.

Which certification should a buyer request for the biodegradable plastic laundry bags?

Buyers should request EN 13432 certification, which verifies that the bag degrades at least 90 % within 90 days in a commercial composting setup.

What are the common dimensions for the agricultural mulch film?

The mulch film is usually rolled in widths of 1‑1.2 m and lengths up to 1 km, with thicknesses ranging from 50 µm to 150 µm, suitable for covering rows of crops.

How are the products typically packaged for international shipment?

Films are wound on core drums or flat rolls, while bags are stacked on moisture‑resistant pallets; both are loaded into standard 20‑ft or 40‑ft containers with interior dunnage to prevent deformation.

What documentation is advisable to obtain before placing an order?

Request a current Material Safety Data Sheet, third‑party test reports for solubility, tensile strength, and biodegradability, and any relevant certificates (FDA, ISO 13485, EN 13432) that correspond to the intended market.

What are typical lead times for these polymer products?

Lead times generally range from 30 to 45 days for standard film rolls and 45 to 60 days for customized medical‑grade laundry bags, depending on order size and required certifications.
