Black PP plastic 28-400 child-resistant pictorial lid

The L336BKH3 is a black polypropylene (PP) plastic child-resistant cap designed for 28-400 neck finish containers, featuring a heat induction seal (HIS) liner suitable for PET and PVC containers. Child-resistant caps require additional effort to open due to a locking mechanism, meeting regulatory standards. The HIS liner, a metallic disk, ensures an airtight, tamper-evident seal when heat induction sealing is applied, offering security for sensitive products.

This closure’s high heat tolerance and fatigue resistance, typical of PP material, make it efficient for industries requiring secure packaging, such as pharmaceuticals or chemicals. Its compatibility with PET and PVC containers enhances convenience and versatility. The child-resistant feature adds an extra layer of safety, making it suitable for businesses handling hazardous or controlled substances, ensuring compliance with safety regulations.

Shipping with the HIS liner pre-inserted, this cap streamlines packaging processes. Commercially, it offers tamper-evident protection, reducing product spoilage and enhancing customer trust. Understanding the 28-400 neck finish and liner types is crucial for optimal use, ensuring a secure fit and seal.
