1. Clarify product features and requirements 

Before customizing solid beverage sealing film, it is necessary to confirm the type of solid beverage (powder, granular or block), ingredient characteristics (whether it contains sugar, acid or easily hygroscopic), and packaging form (canned, bagged or bottled). For example, high sugar products require anti adhesive sealing film, while moisture prone products such as protein powder require high barrier aluminum foil film. 

2. Choose suitable materials and structures 

Powdered beverage: It is recommended to use aluminum foil composite film (such as PET/AL/PE) to prevent oxygen and moisture. 

Granular beverage: Aluminum plated film or pure PE film can be used to balance cost and performance. 

Heat sealing layer: Match the type of adhesive (such as EVA or low-temperature heat sealing adhesive) based on the container material (PP, PET, or glass). 

3. Customized functional design 

Easy to tear opening: laser marking or die-cutting process, convenient for consumers to open. 

Anti counterfeiting label: integrated QR code, holographic hot stamping or destructive opening structure. 

Breathability: Solid beverages that require fermentation (such as enzyme powder) can be customized with microporous breathable membranes. 

4. Process parameter validation 

Provide solid beverage sealing film samples for sealing testing to verify the following parameters: 

Heat sealing temperature (usually 130-180 ℃) 

Pressure (0.2-0.5MPa) 

Sealing strength (≥ 2N/15mm) 

By testing the filling line, ensure compatibility with existing production equipment. 

Suggestions for the customization process of solid beverage sealing film: propose requirements → material selection → sample testing → parameter optimization → mass production. Professional suppliers can provide full technical support to help you achieve efficient and safe packaging solutions.
