K Cups

PP plastic, chemical name: polypropylene English name: Polypropylene (referred to as pp) specific gravity: 0.9-0.91 g/cubic centimeter molding shrinkage rate: 1.0-2.5% molding temperature: 160-220°C PP is a crystalline polymer, PP The overall performance is better than that of PE material. PP products are light in weight, good in toughness and good in chemical resistance. Disadvantages of PP: low dimensional accuracy, insufficient rigidity, poor weather resistance, it has post-shrinkage phenomenon, and after demoulding, it is easy to age, become brittle, and easy to deform. In daily life, the commonly used crisper is made of PP material, which is the raw material for producing K cups. The k-cup is a container that looks like a paper cup, and there is a smaller paper cup-shaped permeation device inside, which can only penetrate liquid. The inside is coffee or tea, and it is sealed with an aluminum foil cover to ensure that the aroma of the coffee will not be emitted. Put the K cup into this coffee machine, press the button, and the pressurized water injection pipe will penetrate the aluminum foil cover and enter the filter cup to inject hot water. The coffee machine precisely controls water volume, water temperature and pressure.
