Of course it's useful! 

Aluminum foil sealing film (induction sealing film) is not unnecessary, but a crucial and cost-effective safety design in modern packaging. It is like an unknown 'security guard', whose role goes far beyond simply 'sealing off'. 

Let me briefly introduce the huge use of aluminum foil sealing film: 

① Security guarantee 

Specific functions: anti-counterfeiting and tamper proof 

Practical benefits: The complete aluminum foil sealing film is the "disposable seal" of the product that has not been illegally opened, ensuring the safety of medication and consumption. 

What would happen without a sealing film: It is impossible to determine whether the product has been tampered with by others, and there is a risk of contamination, exchange, or malicious poisoning. 

② Quality assurance 

Specific functions: Ultimate sealing: moisture-proof, anti-oxidation 

Practical benefits: include effectively blocking water vapor and oxygen in the air, ensuring stable drug efficacy, preventing health products from spoiling, and preventing milk powder and coffee from getting damp and clumping. 

What would happen without a sealing film: drugs may fail, food is prone to moisture and spoilage, flavor and nutritional value are greatly reduced, and shelf life is shortened. 

Specific functions: prevent leakage 

Practical benefits: Even if the bottle cap is loose, the inner aluminum foil sealing film can prevent liquid leakage or powder spillage, keeping the packaging clean. 

What would happen without a sealing film: The product may leak during transportation, contaminate other items, and cause waste and trouble. 

③ Compliance and Trust 

Specific function: Industry standard requirements 

Practical benefits: For industries such as pharmaceuticals and health products, this sealing method is a key factor in ensuring product quality meets regulatory requirements. 

What would happen without a sealing film: the product cannot meet the market standards and the brand reputation will be damaged.
