Structural Composition
Thermoforming aluminum-plastic blister machine: Softens plastic by heating and then forms it. It has a fast forming speed, is suitable for large-scale production, but has slightly lower precision.
Cold forming aluminum-plastic blister machine: Uses prefabricated blister molds to make plastic fit through pressure. It has high precision, is suitable for occasions with special requirements for blister shapes, but has a slightly slower speed.
Main structure and functions
Forming device: Heats and softens plastic sheets and forms blisters under the action of molds.
Heat-sealing device: Heat-seals aluminum foil with formed blisters to ensure the tightness of the packaging.
Feeding device: Used to accurately put products into blisters. Different products need to be equipped with corresponding feeders.
Batch number printing device: Prints product batch numbers, production dates and other information on aluminum foil.
Indentation device: Presses indentation lines on packaging plates for easy tearing.
Blanking device: Blanks the heat-sealed packaging plates into individual blister packaging products.
Working principle
Aluminum-plastic blister packaging machines typically use plastic sheets such as PVC hard sheets, PVDC, PET, and aluminum foil as packaging materials. The plastic sheets are softened by heating and formed into blisters under the action of a mold. Then, the products are placed into the blisters, and aluminum foil is covered over them. The aluminum foil and plastic blisters are tightly bonded using heat-sealing technology, and finally, individual blister-packaged products are obtained through blanking.
Features
Flexible adaptation design: It can adapt to different product shapes by replacing molds and is compatible with various materials such as PVC, PVDC, PET, cold aluminum, etc.
Intelligent control: It usually adopts PLC + touch screen control, which can realize parameter adjustment, production monitoring and data recording, and also has functions such as photoelectric automatic correction, cursor positioning, and stepless speed regulation to improve accuracy and efficiency.
Energy saving and environmental protection: Some advanced aluminum-plastic blister packaging machines adopt fluorine coating uniform heating technology to reduce material waste. Edge-free blanking can save 4%-6% of packaging materials and support biodegradable materials.
Application fields
Pharmaceutical industry: Mainly used for packaging drugs such as capsules, tablets, pills, injections, and medical patches. It can ensure that drugs are sealed and protected from contamination, meeting GMP standards.
Food industry: Can package solid, liquid, or semi-solid foods such as chocolate beans, milk tablets, biscuits, honey, and olive oil, which can extend the shelf life and maintain the flavor.
Daily chemical industry: Suitable for packaging daily necessities and cosmetics such as laundry detergent pods, essence liquids, and lipstick samples, which can enhance product display and prevent liquid leakage.
Electronics and hardware industry: Used for packaging products such as batteries, electronic components, and watch movements, playing a role in moisture resistance, anti-static protection, and prevention of physical damage.
