CPE Regulatory Compliance & Sustainability 4 — Questions and Answers
Question 1: A US company is exporting packaged goods to China. Which Chinese regulation governs packaging waste management and mandatory recyclability requirements for products sold in China?
- GB 18455 Packaging Recycling Standard (Correct answer)
- China RoHS (SJ/T 11363)
- GB/T 16288 Plastic Products Recycling Mark
- China Packaging Law (Order No. 1300)
Correct answer: GB 18455 Packaging Recycling Standard
GB 18455 is China's mandatory standard for packaging recyclability, establishing design and material requirements to facilitate waste packaging recycling.
Question 2: The Toxics in Packaging Clearinghouse (TPCH) model legislation restricts the intentional introduction and incidental presence of which four heavy metals in packaging?
- Lead, mercury, cadmium, and hexavalent chromium (Correct answer)
- Lead, arsenic, barium, and selenium
- Mercury, cadmium, nickel, and antimony
- Lead, mercury, arsenic, and beryllium
Correct answer: Lead, mercury, cadmium, and hexavalent chromium
TPCH legislation, adopted by 19+ US states, restricts lead, mercury, cadmium, and hexavalent chromium with a 100 ppm combined concentration limit.
Question 3: Under the Globally Harmonized System (GHS) for classification and labeling, a secondary packaging that contains a hazardous material must display which information as a minimum on its label?
- Product identifier, signal word, hazard statements, pictograms, precautionary statements, and supplier information (Correct answer)
- Signal word and pictogram only
- Full SDS (Safety Data Sheet) contents
- UN number and packing group only
Correct answer: Product identifier, signal word, hazard statements, pictograms, precautionary statements, and supplier information
GHS requires all six label elements—product identifier, signal word, hazard statements, pictograms, precautionary statements, and supplier identification—on hazardous material labels.
Question 4: In recyclability testing, the APR (Association of Plastics Recyclers) Critical Guidance Protocol for PET bottles defines a package as 'compatible' if it:
- Contains no additives above 1% by weight
- Does not degrade the quality of reclaimed PET resin below acceptable commercial standards (Correct answer)
- Uses only virgin PET resin in the primary structure
- Passes a 30-day biodegradation test in simulated recycle stream conditions
Correct answer: Does not degrade the quality of reclaimed PET resin below acceptable commercial standards
APR's Critical Guidance defines compatibility based on whether the package, when recycled with PET, produces reclaimable PET meeting commercial quality standards for color, IV, and clarity.
Question 5: The US EPA's Safer Choice program certifies packaging-associated materials based on which primary criterion?
- Minimum 50% bio-based content
- All chemical ingredients meet safety standards for human health and environment (Correct answer)
- Carbon neutrality certification from a third party
- Zero VOC emissions during manufacturing
Correct answer: All chemical ingredients meet safety standards for human health and environment
EPA Safer Choice certifies products—including packaging-associated cleaning and coating materials—where every ingredient has been reviewed and meets safety standards for human health and the environment.
Question 6: Which packaging-relevant provision of the US Farm Bill establishes federal procurement preferences for biobased packaging materials?
- BioPreferred Program under Section 9002 (Correct answer)
- USDA Organic Certification under Section 10606
- Rural Energy for America Program (REAP) under Section 9007
- Biomass Crop Assistance Program under Section 9010
Correct answer: BioPreferred Program under Section 9002
The USDA BioPreferred Program under Farm Bill Section 9002 requires federal agencies to prefer biobased products, including packaging, when making purchasing decisions.
Question 7: A packaging engineer must evaluate a multilayer film for recyclability. The most critical factor that typically prevents multilayer flexible packaging from being 'Recyclable' under APR guidance is:
- Total package weight exceeding 500g
- Incompatible resin layers that cannot be separated, contaminating the recovered polymer stream (Correct answer)
- Use of water-based inks on the outer surface
- A minimum of three distinct polymer layers
Correct answer: Incompatible resin layers that cannot be separated, contaminating the recovered polymer stream
Incompatible resin combinations in multilayer films (e.g., nylon or EVOH layers in PE structures) contaminate the recovered polymer stream and render the package non-recyclable in current infrastructure.
