How to determine if a plastic olive oil can is safe?

1. Material Safety
1. Food-Grade Plastic Type
Preferably choose containers labeled PP (polypropylene) or HDPE (high-density polyethylene). These materials are chemically stable and meet food contact standards. Avoid PVC (polyvinyl chloride) or plastics containing plasticizers, as long-term contact with oils and fats may release harmful substances.
2. Light Protection and Sealing
Transparent or translucent plastic cans should be stored away from light to prevent oil oxidation. Dark cans or those with a light-shielding coating are preferred. Containers with poor sealing properties can accelerate oil deterioration. It is recommended to choose a screw cap or a push-on seal design.
2. Certification Standards
1. Domestic Compliance
Must comply with the "National Food Safety Standard for Plastic Materials and Articles for Food Contact" (GB 4806.7-2016), focusing on indicators such as total migration and heavy metal content. Metal-coated plastic cans must also meet the requirements for metal substrates in GB 4806.9-2016. 2. International Certification
Export products must pass FDA certification (such as 21 CFR Part 177) or EU migration testing to ensure that contaminants such as plasticizers and mineral oils do not exceed permitted levels.
III. Usage Precautions
1. Avoid long-term storage: Plastic containers are only suitable for short-term storage (recommended within three months). Glass or stainless steel containers are recommended for long-term storage.
2. Avoid high-temperature environments: Plastic is not heat-resistant. Store away from heat sources such as stoves and heaters to prevent the release of harmful substances.
3. Regular Inspection: Stop use immediately if any deformation, discoloration, or unusual odor is detected.
