① Standardized Biodegradability: Brown paper resealable bags (inner packaging), biodegradable packaging (such as biodegradable PLA film bags), environmentally friendly packaging (such as unlaminated kraft paper bags), and honeycomb mailing bags (outer packaging) must all comply with EU EN 13432 or US ASTM D6400 standards, with a degradation cycle difference of ≤1 month, ensuring simultaneous degradation after disposal and no mixed pollution; ② The source of materials must be uniform and compliant, prioritizing FSC or PEFC certified paper materials, and biodegradable auxiliary materials (such as adhesive strips and coatings) must all be OK Biobased certified, forming a "full-chain sustainable" material system; ③ Environmental labels must be printed uniformly, with all packaging printed with the target market's environmental symbols (such as the EU "Green Dot" logo and US recycling code #27), and the label's position and size must be consistent (such as the lower right corner of the bag, accounting for 5%-8%), to avoid consumer confusion. Uniform Food Contact Safety: If used in Food Packaging, all packaging categories must be certified for food contact safety: ① Brown paper self-sealing bags (for inner food packaging) and biodegradable packaging (such as food-grade PLA bags) must be FDA or LFGB certified; honeycomb mailing bags (for outer food packaging) must be certified for food-grade moisture-proof coatings (such as water-based acrylic coatings) to ensure safety throughout the entire food contact chain; ② Hygiene standards must be uniform. All packaging production workshops must meet GMP cleanroom standards, and finished product hygiene testing indicators must be consistent (e.g., total bacterial count ≤100 CFU/g) to avoid food contamination due to substandard hygiene in any type of packaging.

Brown paper resealable bags (inner packaging) + honeycomb mailing bags (outer packaging) form a "double protection + environmental synergy" in e-commerce small-item shipping scenarios: ① Brown paper resealable bags are used to pack small items (such as jewelry, cosmetic samples, electronic accessories). The resealable design ensures that the goods do not fall apart and can be reused (e.g., for resealing when customers return or exchange goods); ② The honeycomb mailing bag serves as the outer packaging. With the cushioning performance of the honeycomb structure (impact resistance ≥50kJ/m²), it protects the inner brown paper resealable bag and the goods from transportation compression and collision damage, especially suitable for fragile items (such as glass jewelry and small electronic components); ③ The size must be precisely matched. The volume of the folded brown paper resealable bag should be 60%-80% of the internal volume of the honeycomb mailing bag, leaving sufficient cushioning space (e.g., 1-2cm), while avoiding excessive packaging waste, in accordance with the EU's "reduced packaging" requirements.
