When opening packaging in daily life, you may have had the experience that some sealing liners can be easily pulled open completely, while others require effort to find openings or even use tools. 

Easy to tear: The primary goal is the convenience of user experience and the sense of ceremony when opening. 

Non tear type (or tool assisted type): The primary goal is to achieve ultimate sealing, anti tampering, anti-counterfeiting, and security. 

The fundamental difference between the two lies in their physical structure, which directly determines the force and method required for opening. 

1. Easy to tear sealing liner 

Structural features: Usually designed with "pull tab" or "reserved tear opening". The tearing strength of the material itself in a specific direction (such as along the tear opening) is precisely controlled to ensure concentrated force and instant ignition. 

Material technology: In multi-layer composite materials, a tear prone layer is designed, or a clear "tear guiding path" is formed through processes such as laser pre cutting and point cut drilling. 

User experience: Smooth, effortless, crisp and clean opening process, no need for any tools, especially suitable for fast-moving consumer goods and ready to eat products, can greatly enhance consumer favorability. 

2. Non tear sealing liner 

Structural features: Typically a smooth and seamless circular disc as a whole. The composite strength between its various layers of materials (especially aluminum foil and plastic layer) is extremely high, and the material itself has strong tear resistance. 

Material technology: Using high-strength adhesives and tougher base materials, it physically eliminates the possibility of being easily peeled off by hand. 

User experience: It is necessary to use tools such as knives and scissors to puncture or cut open, or rely on the sharp spikes on the inside of the bottle cap to complete the puncture when unscrewing. The process is slightly cumbersome, but it brings a stronger sense of psychological security.
