What is the plastic-free cupstock EPP?

Plastic-free cupstock is made by APP using the unique process of EPP (Environment Protection Polymer). It uses on-machine online coating to replace the single and double coating processes. The product can be directly poured into cups, reducing intermediate links and improving production efficiency; Food packaging made of "zero plastic" coated food cards does not contain any plastic, is completely recyclable, industrially degradable (100%), repulpable, compostable, safe and environmentally friendly.

It has excellent barrier properties(Water based dispersion coating), is waterproof and oil-proof, and is used to make paper cups, soup buckets, etc., to hold ready-to-eat drinking water, tea, beverages, milk, milk tea, coffee, etc.

EPP is suitable for flexo printing, but not suitable for offset printing processes; the ultrasonic wave of a medium-speed cup making machine can bond normally; the heat sealing temperature of the bottom of the cup should set at 380-400°C; the watering time of the cup piece should be controlled at 0.5-1 hour, if it is too long, it is easy to tilt the head.

 

Notes:
1) The storage environment should be ventilated, dry, and avoid paper adhesion caused by high temperature and high humidity environment;

2) After die-cutting, the cup pieces should be protected with wrapping film in time, and the cup pieces should be used immediately after being soaked with water to prevent the cup pieces from becoming hard and sticking after getting wet;

3) Heavy ink volume, large field printing or offset printing should be varnished simultaneously to avoid ink smearing when the cup body is stacked;

4) The taper of the cup should be as large as possible, and the height of the cup bottom should be as high as possible to avoid difficulty in removing the cup after forming and packaging.
