The 38-400 Snap Top Cap is a versatile, high-quality closure designed for bottles with a 38-400 or 38-405 neck finish. Its flip-top design allows for convenient dispensing, making it ideal for a variety of liquid and dry products.

Material and Benefits of Polypropylene Caps

The 38-400 Snap Top Cap is made from polypropylene (PP) plastic, a durable and lightweight material known for its chemical resistance and flexibility. PP plastic is commonly used for packaging due to its high heat tolerance and ability to maintain its structure under various environmental conditions.

• Chemical Resistance – Polypropylene resists degradation from oils, acids, and alcohol-based liquids.
• Durability – Impact-resistant and designed for frequent use without cracking or breaking.
• Lightweight & Cost-Effective – Reduces shipping costs while maintaining structural integrity.
• Recyclability – An eco-friendly choice for sustainable packaging.

Benefits of Pressure-Sensitive Liners

This snap top cap includes a pressure-sensitive liner, a key feature for sealing and preserving product freshness. Unlike induction liners, pressure-sensitive liners adhere to the bottle’s rim simply through applied pressure, forming an instant seal after the cap is screwed on.

• Tamper-Evident Protection – Provides visible assurance that the product has not been opened before purchase.
• Extended Shelf Life – Prevents leakage and protects against contamination.
• No Special Equipment Required – No heat-sealing machinery needed, making it a cost-effective solution.
