Material safety is the foundation of any plastic storage product. For B2B buyers serving consumer markets, especially in North America and Europe, understanding plastic resin codes and certification requirements is non-negotiable. Let us break down what these codes mean and which materials are appropriate for different use cases.
Plastic Resin Codes Explained: The numbering system (1-7) printed on plastic products identifies the type of resin used. For storage drawers, the most common and safest options are:
Plastic Resin Codes for Storage Drawers: Safety and Applications
| Code | Material | BPA-Free | Heat Resistance | Best For | Cost Level |
|---|
| 1 (PET) | Polyethylene Terephthalate | Yes | Low (avoid hot liquids) | Clear transparent drawers, light storage | Low |
| 2 (HDPE) | High-Density Polyethylene | Yes | Moderate (up to 120C) | General purpose storage, chemical resistance | Low-Medium |
| 4 (LDPE) | Low-Density Polyethylene | Yes | Low (softens 80-90C) | Flexible drawer liners, soft components | Low |
| 5 (PP) | Polypropylene | Yes | High (microwave-safe) | Food storage, premium drawers, heat exposure | Medium |
| 6 (PS) | Polystyrene | No | Low (releases styrene when heated) | Avoid for storage applications | Lowest |
| 7 (Other) | Mixed/Other plastics | Varies | Varies | Specialty applications only | Varies |

[1]PP (Polypropylene, Code 5) is widely regarded as the safest option for food-contact applications. It offers the highest heat resistance among common plastics, is microwave-safe, and does not leach harmful chemicals even under temperature stress. For premium storage drawers targeting health-conscious consumers, PP should be your default choice.
HDPE (High-Density Polyethylene, Code 2) provides excellent chemical resistance and moderate heat tolerance. It is commonly used for general-purpose storage drawers where food contact is not expected. HDPE offers good durability at a lower cost point than PP, making it suitable for budget-conscious market segments.
PP and Tritan are the safest options that avoid harmful chemical leaching and remain stable under high heat. For kitchen containers and food storage applications, these materials should be your priority specification [1].
FDA Certification Requirements: For products marketed as food-safe in the United States, compliance with FDA 21 CFR 177.1520 is mandatory. This regulation specifies the conditions under which plastic materials can safely contact food. Key requirements include migration testing with a threshold of 0.5 ppb for harmful substances and a 120-day Food Contact Notification review process [1].
Important Note on Recycled Materials: While sustainability is increasingly important, buyers should be aware that recycled LDPE loses its food-safe status. If you are marketing eco-friendly products with recycled content, clearly communicate intended use cases and avoid food-contact claims unless specifically certified.
Industry Trend: 95% of new plastic drawer products launched in 2025 are BPA-free. FDA-certified food-safe options represent 15-16% of the market, with growing demand from health-conscious consumers and institutional buyers
