1) Product Overview
+Product name: Eco Hero – children's safety helmet made from bioplastic combined with bamboo fiber.
+Purpose: Inspire children to become “green heroes” – wearing safety helmets, learning about environmental protection and using sustainable materials.
2) Size & Form
+ Head circumference: 50 – 54 cm (standard for children 6–10 years old).
+ Length (forehead → nape): 24 – 26 cm.
+ Width (ear → ear): 18 – 20 cm.
+ Crown height: 13 – 15 cm.
+ Shell thickness: ~2.5 mm (thicker than standard ABS to compensate for the mechanical properties of bioplastic).
+ Target weight: 230 – 265 g.
+ Liner foam pad: 1.5 – 2.0 cm, with a 0.8–1.0 cm air cavity to ensure air circulation and reduce stuffiness.
3) Materials
A. Outer shell
+ Bioplastic bamboo-fiber PLA (Polylactic Acid + crushed bamboo fiber) – 30% recycled bamboo fiber to increase durability and reduce plastic.
+ Natural colors (bamboo beige, light green), can be coated with water-based paint or printed with “Eco Hero” motifs to create a superhero image.
+ EN13432 certified for compostable/bio-degradable (self-degradable under industrial conditions).
B. Impact absorbing layer (Liner)
+ Recycled EPS/EPP: at least 30% recycled particles, density 40–80 kg/m³.
+ Multi-compartment design reduces impact force, supports impulse dispersion.
C. Inner cushion (Comfort pads)
+ Bamboo-blend natural fabric: combining bamboo fiber + organic cotton.
+ Natural antibacterial, good moisture absorption, easy to remove and wash, reduces odor.
D. Retention system
+ Recycled PET or recycled nylon strap, side-release lock made of recycled polyacetal.
+ Has a dial-fit or simple drawstring system for quick adjustment.
4) Safety & Features
+ Bioplastic has been mechanically tested to meet durability standards equivalent to ABS.
+ Water-based paint is completely non-toxic, does not contain VOC or heavy metals.
+ Odorless material, smooth surface, easy to clean with warm water.
Safety standards:
+ Impact test according to EN1078 or TCVN 5756:2015.
+ Retention & strap strength ensures traction according to European standards.
+ Chemical migration test to ensure safe contact for children.
5) Testing & Certification
+ EN13432: Compostable/Biodegradable.
+ EN71-3: Safe contact for children.
+ ISO 14001: factory (if applicable) to demonstrate environmental management.
+ Carbon Footprint assessment: 40% less than a regular ABS helmet.
6) Lifespan & Warranty
+ Lifespan: 3–5 years under normal use; bioplastic is stable in the environment of use, only degrading when put into industrial composting conditions.
+ Warranty: 12 months for shell and strap.
+ It is recommended not to expose continuously to sunlight > 60°C to avoid aging of PLA.
