Common materials: corrugated paper, cardboard.

Performance requirements: a certain cohesion and bonding strength; reasonable opening time; able to adapt to automatic coating equipment; with product storage environment, adapt to different temperature changes.

 

Consideration points:

1) Resilience, folding method and surface anti-breaking strength of corrugated board of different grades;

2) Film on the cardboard surface;

3) Coordination of the opening time, curing time and pressing time of the glue;

4) Carton pressing method (such as fixed type, spring type);

5) Stacking method, loading weight, use temperature and other conditions;

6) Temperature of the filled items

 

APPLICATION THREE: For Box/ Colored box sealing

Industries invloved: face carton, instant noodles, biscuit boxes, wine, condiments, cigarette boxes, pill boxes, ice cream cones, paper buckets, candy boxes, gift boxes, etc.

Common materials: coated paper, pit paper, white cardboard, kraft paper, cardboard or PP, PET, PVC, PE, etc.

Performance requirements: green, no pollution; suitable opening time, able to adapt to automatic coating equipment; with product storage environment, adapt to different temperature changes.

Consideration points:

1) Paper contact surface: water-based, oily glazing; UV glazing; PE, PP glazing (film coating)

2) Temperature at the filling: eg: soy sauce (about 40 ° C); sweet and spicy sauce (about 50 ~ 70 ° C); vinegar (about 65 ~ 70 ° C); sand tea sauce (90 ° C); oil / lubricant (40 ~60 and 90 °C)

3) Ambient temperature: low temperature storage, high temperature baking, etc.
