“Quality Inspection and Certification of PP Plastic Packaging” (Including Thai Industrial Standards – TIS)

Why Quality Assurance Matters for PP Packaging?

Polypropylene (PP) plastic is widely used in the packaging industry, especially for food containers, due to its heat resistance, safety, and durability. However, to ensure consumer protection and compliance with regulations, PP packaging must undergo proper quality inspections and certification.

Relevant Standards for PP Packaging

1. Thai Industrial Standards (TIS)

The Thai Industrial Standards Institute (TISI) has established several important regulations related to plastic packaging, particularly for food contact materials:

• TIS Code

  Description
• TIS 816-2556

  Plastic materials for food packaging – General safety
• TIS 1700-2548

  Recycled polypropylene (PP) plastic products
• TIS 2921-2560

  Plastic food containers for use in microwave ovens
• TIS 655-2552

  General specifications for plastic containers
• TIS 2493-2564

  Polypropylene plastic containers for food contact

This is a key standard that specifically governs the use of PP plastic for food packaging. It includes requirements for chemical migration, physical properties, and thermal resistance to ensure food safety.

TIS 2493 is considered the most essential standard for PP plastic packaging used in direct food contact in Thailand.

2. International Standards

• Standard

  Description
• FDA (USA)

  PP plastic is approved as a food contact material
• EU Regulation 10/2011

  Regulations for plastic materials in contact with food (EU)
• ISO 9001

  Quality management system certification
• GMP / BRC Packaging

  Food-grade hygiene standards for packaging production

Typical Quality Inspection Process

• Step

  Description
• Raw Material Verification

  Use certified food-grade PP resin with Certificate of Analysis (COA)
• Migration Testing

  Ensure no harmful substances leach into food
• Physical Testing

  Evaluate thickness, sealing, heat resistance, and impact strength
• QC Sampling

  Quality check for each production batch per ISO/GMP standards
• Documentation

  Provide TIS 2493 certification, Test Reports, COC, and Food Grade Certificates

Who Should Prioritize Packaging Certification?

• Packaging Manufacturers :– To build credibility and avoid legal risks
• Brand Owners : – To ensure product safety and consumer trust
• Exporters :– To comply with international regulations and customs requirements

High-quality PP plastic packaging is not only about durability or cost-efficiency — it must also be certified safe for its intended use, especially in food-related applications. Adhering to TIS 2493-2564 and international food safety standards ensures long-term trust, brand integrity, and compliance with both local and global markets.
