Know about the milk carton
1 Milk carton structure: PE, cardboard, aluminum foil
Milk carton construction function:
Cardboard: Strengthens the hardness of the packaging after it is formed.
Aluminum foil: protects from light and blocks ventilation, keeps the contents from
being oxidized, reduces nutritional loss, and keeps the taste fresh.
PE: The outermost layer of PE is mainly used for printing. The PE on the inside also
acts as a heat seal to prevent liquid leakage and microbial invasion.
2 Why do we use milk cartons as recycled paper experiments?
Jinan Quanhua is a very socially responsible company and has been
committed to promoting the recycling and reuse of milk cartons.
The pulp in milk cartons can be said to be pulp made from the best forests
on the planet, so we only use milk cartons for recycling. Paper experiment.
This kind of pulp is very high-quality and valuable, so the recycling rate in
European and American countries is about 50% or more. In some countries,
such as Japan, the recycling rate exceeds 70%. One ton of milk cartons can be
recycled into 750 kilograms of high-quality recycled paper. , this is what we call
urban minerals (trash is misplaced treasure).

4 Why are milk cartons square?
The first reason why milk boxes are made into square shapes is because milk
needs to be sterilized, so it is often packaged in roof boxes. That's right,
it's this roof-like package (pictured)
This packaging is a composite material of paper, polyethylene, and aluminum foil,
which is similar to the properties of paper. The best structure for paper is a square shape.
So why are there no round paper bottles made of paper? First, due to technical reasons,
large-scale mass-produced round bottles cannot be made from paper. It's because of cost.
Since milk needs to be refrigerated and stored, a freezer is required, and the storage cost is
higher than that of ordinary shelves. Square shapes save more space than round shapes and
can store more products.
