Yangzhou Guanyu Plastic Tube Co., Ltd. is located in Jiangsu, 300km away from Shanghai Port.
We are engaged in the production of plastic tubes, which are widely used for cosmetic, pharmaceutical and food packaging. We are specialized in the production of tubes with diameters ranging from 13mm to 60mm, capacity from 3ml to 500ml, layer from double to five, and shape from Round to Oval flat.
We have five co-extruded high speed tube drawing machines, 1-6 color offset printing machines, silkscreen printing machines and foil hot-stamping machines. Looking forward to forming successful business relationships with clients around the world in the near future.
With pump head to ensure uniform and smooth liquid extrusion, materials meet relevant hygienic standards, heavy metals, fluorescent agents and other harmful substances should be controlled within the specified range, the tube body is thick, corrosion resistant, strong barrier, fragrance retention, oxygen permeability Low overrate
The oxygen transmission rate of the single-layer tube is 150-300 units. EVOH is an ethylene-vinyl alcohol copolymer with excellent barrier properties and fragrance retention (the thickness of 15-20 microns is ideal); the double-layer tube: High-density HDPE and LDPE low-density PE materials are used, and the pipe is matched in a certain proportion, and the effect of mixing is achieved by high-speed rotation
On the one hand, it can prevent foreign substances from intruding into the cosmetics and prevent the cosmetics from oxidizing and deteriorating. At the same time, it can prevent the moisture or fragrances in the cosmetics from diffusing to the outside through the hose, thereby ensuring the quality of the cosmetics.
