The ease of tearing of sealing film is not a trivial detail, but a key indicator that directly affects user experience, product image, and even safety. 

It strikes a precise balance between "absolute sealing" and "user-friendly". Its importance is mainly reflected in the following aspects: 

1. The core of user experience and brand impression 

Convenience and frustration: A difficult to tear sealing film can instantly reduce the user experience. When users need to bite with their teeth, cut with scissors, or even seek help from others, it only brings a sense of frustration. On the contrary, the smooth tearing experience makes people feel worry free and happy. 

The embodiment of brand image: A carefully designed easy to tear sealing film reflects the brand's attention to details and respect for users. It silently conveys signals of "high quality" and "humanization". On the contrary, a poor experience can make users doubt the professionalism of the brand. 

2. Safety and controllability 

Preventing content splashing: For carbonated beverages, carbonated yogurt, or some liquid products, if the sealing film suddenly ruptures or tears uncontrollably, it can easily cause content splashing, dirtying clothing or the environment. Controllable and gradual tearability can effectively avoid this problem. 

Avoid packaging damage: Sealing film that is too difficult to tear may cause users to exert too much force, resulting in deformation of the packaging box, tilting of the bottle body, and even scratching themselves due to slipping hands. 

3. Production efficiency and cost 

Production line efficiency: On automated production lines, sealing films need to be accurately picked up and placed by robotic arms. If the film material is too soft, too sticky, or prone to deformation (related to tear resistance), it can lead to poor feeding and inaccurate placement, reducing production efficiency. 

Reduce scrap rate: A well-designed easy to tear sealing film with a controllable tearing path. If the film separates, breaks, or leaves residue when the user tears it open, it may cause the product to be contaminated or complained about, increasing the cost of returns and after-sales service.
