Release time：

04 Jul,2025

Introduction:
Against the global backdrop of frequent pharmaceutical safety incidents, packaging integrity is directly related to patient life and health. As a long-lasting classic solution in the medical packaging field, Aluminum-plastic combination caps With their irreplaceable sealing, material compatibility, and pierceability, they continuously provide ultimate protection for high-risk pharmaceuticals such as injections, infusion bags, and lyophilized powder injections. Yantai Xiehe Huigao Packaging Technology Co., Ltd. has been deeply involved in the industry for 20 years, reshaping the safety standards of aluminum-plastic caps with precision manufacturing processes.

I. Why is the medical field inseparable from aluminum-plastic caps?

▶ Triple protection mechanism

Protection Level	Technical Principle	Medical Value
Physical Barrier	Aluminum cap mechanical strength + plastic cap toughness	Resist transportation impact and prevent bottle breakage
Gas Seal Lock	Medical-grade butyl rubber liner, heat-sealed aluminum foil seal	Blocks oxygen/moisture, ensuring drug stability
Aseptic Guarantee	Pre-disinfection of the piercing area, self-sealing of the stopper	Avoid microbial contamination during drug preparation

▶ Guardian of Lethal Scenarios

Chemotherapy drug preparation : Prevent leakage of toxic substances from harming medical personnel

ICU emergency medication : Ensure aseptic puncture within 1 second during rescue

Biopharmaceutical storage : Maintain seal integrity even at -80℃ frozen storage

II. Technological Evolution: From Basic Sealing to Intelligent Safety
