What are the applications of PVC heat shrink bottle caps in pharmaceuticals, cosmetics, chemical and industrial products?

III. Pharmaceutical, Health Products, and Cosmetics Industry

Oral liquids, medicinal wines, and health supplements:

  As an outer seal, it ensures the product remains unopened before reaching consumers, guaranteeing safety and hygiene.

2. Cosmetics (perfume, skincare products, hair care products, etc.):

   Used for sealing glass bottles or high-end plastic bottles to prevent product sampling or substitution, while exquisite printing significantly enhances the product's sense of refinement and luxury.

IV. Chemical and Industrial Products

1. Premium lubricating oil, automotive care fluids:

   Ensure the original quality of the product and prevent counterfeit or substandard products from being mixed in.

2. Chemical reagents and laboratory supplies:

   Provide basic sealing and opening identification to ensure the reagents remain uncontaminated and unmisused.

V. Other Special Applications

Gift and Souvenir Packaging:

   Used for packaging specialty wines, crafts, and bottles, with customized printed patterns to enhance the exclusivity and ceremonial feel of gifts.

2. Donations or special event supplies:

   One-time sealing ensures the purity and formality of the contents (such as commemorative wine).

Important Trend Tips:

Although PVC heat shrink bottle caps are widely used, the current global environmental regulations are becoming stricter, and consumers' environmental awareness is increasing. Therefore, in many high-end markets and new products, its application is gradually being replaced by more environmentally friendly PETG heat shrink films. PETG, while maintaining all the performance advantages of PVC, has become the mainstream direction for future development due to its recyclability, incineration, and non-toxic (chlorine free) properties. Many brands prioritize eco-friendly materials such as PETG when upgrading their packaging to enhance their brand image and comply with regulatory requirements.

Summary: The widespread application of PVC heat shrink bottle caps stems from its ability to solve core needs such as anti-counterfeiting, sealing, safety, and brand display in the circulation process at a lower cost and in a one-stop manner. It has become a classic packaging standard, especially in industries with high requirements for anti-counterfeiting (such as Chinese Baijiu).
