Production requirements and technical specifications for environmentally friendly paper drums

1、Material selection criteria

Substrate requirements: Use 100% renewable wood pulp or bamboo pulp cardboard, comply with FSC (Forest Stewardship Council) certification standards, and prohibit the use of chlorine bleach.

Auxiliary materials: water-based environmentally friendly ink printing, adhesive needs to pass the EU EN 13432 composting and degradation certification, metal accessories need to be detachable and recyclable.

Lining treatment: Food grade contact requires the use of PLA (polylactic acid) film or silicone coating to replace traditional polyethylene plastic.

2、Production process specifications

Molding process: Adopting integrated molding technology to reduce the production of scraps, the waste recycling rate needs to reach over 95%.

Energy consumption control: Production equipment should be equipped with a heat recovery system, and the energy consumption per unit product should not exceed 0.8 kWh/kg.

Printing process: Using flexographic printing technology, the VOC emissions must be less than 50mg/m ³, in compliance with GB 38507-2020 standard.

3、Performance and quality indicators

Physical strength: Vertical compressive strength ≥ 800N (standard bucket with a diameter of 20cm), passing three drop tests at a height of 1.2m without rupture.

Moisture resistance: Under a humidity of 90% for 48 hours, the deformation rate is less than 3%.

Safety certification: It is required to pass FDA and LFGB food contact material testing, with a heavy metal migration of less than 0.01mg/dm ².

4、Environmental compliance requirements

Life cycle assessment: Provide a full lifecycle carbon footprint report, with each paper bucket emitting no more than 200g CO ₂ equivalent of carbon.

End of pipe treatment: The product must be clearly labeled with the "household compostable" or "industrial grade degradable" label, and the natural degradation rate must reach over 90% within 6 months.

Supply chain traceability: Establish a raw material traceability system to ensure that the source of each batch of pulp can be traced.
