Glass bottles, as high-end, environmentally friendly, and high-quality packaging materials, are highly favored by industries such as food, beverage, and cosmetics. Can it perfectly fit when it encounters aluminum foil sealing film, which is also known for its excellent sealing performance? The answer is yes, but it contains precise scientific adaptation requirements. 

Aluminum foil sealing film can not only seal glass bottles, but also achieve high-quality sealing with high airtightness and strong barrier properties. The key to its success lies in solving the characteristic challenges of glass bottle mouths and achieving them through professional film material selection and precise process control. 

The glass bottle mouth may seem smooth, but there are actually two major challenges: 

The material is hard and non porous: it cannot be embedded by hot melt like plastic bottles. 

Microscopic unevenness and errors: There are tiny bumps, scratches, or size fluctuations that are difficult to detect with the naked eye. 

Aluminum foil sealing film, through its unique multi-layer composite structure, especially the heat sealing coating, can flexibly fill these micro unevenness, thereby achieving reliable sealing. 

Why choose aluminum foil sealing film to seal glass bottles? 

Excellent sealing and preservation: The aluminum foil layer provides almost perfect oxygen, moisture, and light blocking protection, greatly extending the shelf life of products, especially suitable for high-end edible oils, health products, infant and toddler food, high-end seasoning sauces, etc. 

Enhance product grade: The metallic texture and crystal clear glass complement each other, coupled with exquisite printed patterns, significantly enhancing the product's appearance value and sense of consumer ceremony. 

Excellent opening experience: The easy to tear design makes it convenient for consumers to open, while leaving obvious opening marks and providing basic anti-counterfeiting functions. 

Adapting to high-speed production lines: Mature electromagnetic induction sealing technology can achieve high-speed and automated sealing production of glass bottles. 

Important considerations and selection suggestions 

When selecting aluminum foil sealing film for glass bottles, please make sure to clarify the following information with the supplier: 

1. Bottle mouth size and tolerance: Accurate bottle mouth inner diameter, outer diameter, and height are the basis for customizing molds. 

2. Content properties: Is it water-based, oily, acidic, or alcohol containing? This directly determines the formula selection for the heat sealing coating. 

3. Subsequent process requirements: Do you need to withstand high temperature steaming, pasteurization, or cold chain storage? 

4. Opening method: Do you need to fully tear open the easy to tear type or leave a mark anti-theft type?
