automatic blister packaging machine packaging Material characteristics

Guangdong Rich Packing automatic blister packaging machine can pack differnet items into alu-alu or alu-pvc,it is a dual purpose machine

1. Plastic

The main materials used in Guangdong Rich Packing automatic blister packaging machines are cellulose, such as cellulose acetate, cellulose butyrate, and cellulose propionate; styrene, such as uniaxially stretched polystyrene (OPS), impact-resistant polystyrene ( PS); Vinyl, such as plasticized soft PVC, non-plasticized rigid PVC; PE,polyester film.

The key to the design of Guangdong Rich Packing automatic blister packaging machines is the selection of the properties, grades and thickness of the blister material film. Generally speaking, the choice of rigid film should consider its impact resistance, aging resistance, migration (that is, the penetration effect of PVC components on product quality), the adaptability of the material to the product, cost, heat sealability .Easy cutting and finishing of the product.

2. Heat seal coating

The heat sealing coating is applied to the web material by the gravure coating method, rubber plate coating method, screen coating method or combined spraying method. The coating amount of the heat sealing coating on the cardboard or PVC film base should be appropriate, so that the entire blister package has the best heat-sealing effect.

The main properties of flux-based vinyl coatings are hot tack, sealing temperature, gloss, rheology, fluidity, etc. The heat-seal coating must be compatible with both cardboard or plastic sheet-based blister. Only suitable coatings have good adhesive strength. For example, the coating material used for cellulose acetate blister is completely different from the coating material used for polystyrene blister.

3. Printing ink

The printing ink on the Guangdong Rich Packing automatic blister packaging machines have a high heat-resistant sealing temperature (230～250℃), abrasion resistance, folding resistance, no fading, and good safety (it should not contain excessive hydrocarbon grease and anti-sticking agent) .

4. Cardboard

The cardboard is selected by the size, shape, weight and packaging style of the product. The thickness of the cardboard used for blister packaging is 0.36～0.76mm, the most commonly used is 0.46～0.61mm. After heat sealing the cardboard and the blister, the adhesive strength should be greater than the fiber tear strength. The cardboard must have good printability and coatability. The purpose of the white clay coating layer on the cardboard is to improve the printing effect and heat-seal impermeability.
