Aluminum foil sealing gasket is an important component to ensure packaging sealing in industries such as food, medicine, and cosmetics. However, improper operation may lead to issues such as weak sealing, leakage, or contamination. Today, we will introduce the key points to pay attention to when using aluminum foil sealing gaskets, helping you optimize the sealing process and ensure packaging quality.

1. Bottle mouth cleaning is the key to success or failure

Many people think that as long as the gasket quality is good, it is enough, but in fact, the invisible oil film and water stains on the bottle mouth are the main culprits of sealing failure

Simple and effective solution: Wipe the bottle mouth with an alcohol swab and then blow it with compressed air Special attention: The hand cream on the operator's hands may contaminate the bottle mouth, and they must wear finger cots during operation

2. The higher the temperature, the better

Common misconception: Thinking that increasing the temperature can seal it more firmly, resulting in the gasket being deformed due to overheating

Golden rule: PE material bottles should be tested from 160 ℃, PP material should be tested from 180 ℃

Tip: After sealing, wait for 3 seconds before tearing to quickly determine if the temperature is appropriate (there should be slight resistance when tearing)

3. The new batch of gaskets must be tested for sealing

The actual performance of gaskets from different batches may vary

Key observation during sealing: whether the sealing edge is flat and whether there is a uniform aluminum layer residue when tearing open

It is recommended to try sealing 20-30 samples each time a new roll of gasket is opened

Special reminder: If there is a leakage of gas only a few days after sealing, it is likely that there has been a chemical reaction between the gasket and the contents, and the supplier needs to be contacted to replace the gasket with a special material.
