Nowadays, plastic jars with tear-off edge LIDS are very common. Their functions are multi-faceted, mainly focusing on sealing, convenience and safety.
 

1. Ensure initial sealing and product freshness: This is the most crucial function, as the plastic jars here mainly store powder products. Before the consumer opens it for the first time, the tear-off edge cover (usually combined with a layer of aluminum foil or plastic film) forms a completely airtight and water-tight seal, isolating air: effectively preventing oxygen from entering, avoiding oxidation, moisture absorption, deterioration or loss of aroma of the contents (such as food, protein powder, coffee powder, medicine), thereby ensuring the freshness and shelf life of the product.

2. As a basic design for secondary sealing LIDS: tear-off edge LIDS are usually used in conjunction with reusable jars. After removing the sealing layer, the remaining can mouth is smooth and flat, which enables the main opening and closing cover at the top to be tightly fastened, achieving secondary sealing.

3. Evidence of tampering: Remove the lid as a seal to ensure that the interior of the product has not been tampered with. Once the seal is broken, it provides a clear sign that the can has been opened, which is crucial for the storage of food items. Consumers must ensure that they receive the latest product.

4. Easy to open: The tear-off edge lid allows for easy opening of the jars. After the first tear of the pull TAB, frequent visits are required without the hassle of repeatedly unscrewing the lid. The main cover is in a snap-on form, which is very suitable for storing items such as protein powder and medicines, as these types have a very high opening frequency. The tear-off edge cover design is a relatively user-friendly opening method.

5. Clear opening experience: It provides users with a clear and intuitive opening action - "Find the pull ring and then tear it open." This clear instruction reduces users' confusion and frustration.

 

The above are the main functions of the tear-off edge lid jar. So, what are the main applications of this type of jar?
