⭐️ Introduction

With consumers’ increasing concern for product quality and safety, how to effectively prevent products from being illegally opened or contaminated during transportation, sale and use has become an important issue in packaging design. Especially in the food, drugs, cosmetics and other industries directly related to human health, packaging not only carries the basic container function, but also a key barrier to protect the integrity of the product and consumer safety. In this context, tamper-evident packaging has emerged and gradually become an industry standard.

This paper aims to systematically discuss the key technologies, application scenarios, and future development trends of tamper evident glass vials. By analyzing and evaluating the current mainstream tamper-resistant mechanisms, this paper hopes to provide relevant industries with design ideas and technical references that can be drawn upon to further enhance the safety and credibility of product packaging, and to effectively protect the legitimate rights and interests of consumers.

⭐️ Key Technologies for Tamper Evident Glass Vials

In order to effectively prevent products from being opened, replaced or contaminated without authorization, tamper evident glass vials introduce a variety of technical means in the design and manufacturing process, which can be divided into two main categories: physical tamper evident design and chemical tamper evident means.

1. Physical tamper-proof design

Physical anti-tampering is currently the most widely used and relatively low-cost means, mainly by changing the structure of the packaging or mentioning the irrecoverable physical components, so that the opening behavior is irreversible, and can intuitively reflect whether the product has been opened.

Disposable bottle cap: disposable bottle cap is one of the most typical physical anti-tampering measures. Commonly, there are broken ring, anti-theft ring structure, in the first time to open the bottle cap, the ring structure under the cap will automatically break or fall off, can not be recovered, so that the line test good sad obvious traces of opening. This kind of bottle cap is widely used in the field of beverage, alcohol and medicine.

Heat-shrinkable film or sealing film: Heat-shrinkable film is wrapped around the bottle mouth or bottle cap, which is tightly adhered to the bottle body through heat treatment, and cannot be recovered once it is torn open, thus becoming an irreversible open seal mark. The sealing film is mostly used for the mouth of medicine or cosmetic bottles. Destroying the sealing film is equivalent to directly destroying the integrity of the product, which has a strong visual warning effect.

2. Chemical tampering

Chemical tampering is achieved by special treatment of materials and labels so that any attempt to open, replace or affix them leaves a trace that cannot be concealed. These means are often used as a complement to physical protection to improve the recognition of tampering.

• • Special inks or labels: Using inks that change color when exposed to air, moisture, light, or friction, such
