Jilian Mold Production Of Completely Assured China Pet Bottle

Posted by nicolepreform on Mär 13, 2019 in News

(1) When designing extruded Pet Preform, if the material is made of high-density polyethylene or polypropylene, the cross-section of the pet bottle should be rectangular or elliptical, for low-density polyethylene or other flexible pet bottles. The cross section is preferably a circle. This facilitates the extrusion of the contents from the pet bottle. The pet parts used in conjunction with the pet bottle mouth are mainly caps and seals. The design of the pet bottle opening should focus on how to make the pet bottle mouth better fit the lid and sealer. The bottom of the pet bottle is the weak part of the mechanical properties of the pet bottle. Therefore, the bottom of the pet bottle is generally designed to be concave; the corners of the pet bottle and the inner recesses are all excessively curved. In order to facilitate the stacking of pet bottles, increase the stacking stability of pet bottles, and the inner bottom of pet bottles should be designed with inner grooves.
(2) When the surface of the pet bottle is marked with a label, the surface of the label should be flat. A “sash” can be designed on the surface of the pet bottle to make the label accurately positioned without moving. At the time of blow molding, the portion where the parison inflates first contacts always tends to be hardened first. Therefore, the wall thickness of this part is also larger. The edge and the corner portion are the portions where the parison inflates the last contact, and the wall thickness of the portion is small. Therefore, the edges and horns of the pet bottle should be designed to be rounded. Change the surface shape of the pet bottle, such as the middle of the pet bottle is relatively thin, increase the circumferential groove or rib of the surface of the pet bottle, can improve the rigidity and bending resistance of the pet bottle. Longitudinal grooves or ribs eliminate the offset, sagging or deformation of pet bottles under long-term load.
(3) The printed surface of the pet bottle is the most concentrated part of the consumer’s attention. The printing surface should be flat and continuous; if the pet bottle contains handles, grooves, ribs and other structures, care should be taken not to inconvenience the printing operation. The oval pet bottle has a higher rigidity, but the manufacturing cost of the mold is higher. Therefore, in order to ensure the rigidity of the pet bottle, in addition to selecting the material with high rigidity, the shape of the pet bottle should be designed to enhance the rigidity and load resistance of the pet bottle.
(4) Since most pets have notch sensitivity, pet bottles are prone to cracks and cracks at sharp corners, roots of the mouth thread, neck, etc., so these parts should be designed to be rounded. For the transfer point of the rectangular pet bottle, it is necessary to support most of the load of the pet bottle, so locally increasing the wall thickness at this place is also advantageous for improving the rigidity and load resistance of the pet bottle.

Application And Recycling Of Pet Preform

Posted by nicolepreform on Mär 8, 2019 in News

Pet bottles are not only widely used in the packaging of carbonated beverages, water, juices and tea beverages, but are also the largest use of beverage packaging today, and are widely used in many fields of food, chemical, pharmaceutical and packaging.

Pet has a wide range of applications in the packaging industry, whether it is packaging film, sheet or beer bottles, use pet. But when these materials are discarded, they face the problem of how to deal with tens of billions of China Pet Bottle every year. It is expected that in the next five years, 50 million tons of PET will be used to make pet bottles every year. Therefore, pet bottle recycling can not only solve environmental problems, but also serve as a new raw material resource to alleviate the contradiction of shortage of PET raw materials in China.

Yes, in reviewing China’s 30 years of reform and opening up, China has made remarkable achievements in the economic field, but it has also caused very serious damage to the Chinese environment. Water pollution, air pollution, solid waste pollution, etc. The Chinese economy has shrunk. People have gradually realized this problem, and accordingly put forward a series of measures such as the strategy of sustainable development of green GDP and the circular economy strategy. Therefore, recycling pet bottles meets the real problems faced by China and has great benefits for environmental protection, resource conservation and sustainable development.

The physical recycling method of the pet bottle is relatively simple, mainly to dry and granulate the Pet Preform waste. The physical handling of pet bottles is closely related to the sorting process.

There are two main methods of physical recovery:
First, the discarded pet bottle is chopped, and HDPE, aluminum, paper and binder are separated from the PET and PET chips, and then washed, dried, and granulated;

Satisfied China Pet Bottle

Posted by nicolepreform on Mär 1, 2019 in News

The rheology of PET in molten state is better, and the effect of pressure on viscosity is greater than temperature. Therefore, the fluidity of the melt is mainly changed from pressure.

1. Processing of plastics Because PET macromolecules contain a lipid group and have certain hydrophilicity, the pellets are sensitive to water at high temperatures. When the moisture content exceeds the limit, the molecular weight of PET decreases during processing, and the product is colored. Become brittle. Therefore, the material must be dried before processing, and its drying temperature is 150 ° C, 4 hours or more, generally 170 ° C, 3-4 hours. Airborne methods can be used to verify that the material is completely dry. The proportion of recycled materials should not exceed 25%, and the recycled materials should be thoroughly dried.


2. The selection of PET for injection molding machine is short due to the short time after melting point, and the melting point is higher. Therefore, it is necessary to select an injection system with more temperature control sections and less self-friction heat during plasticization, and the actual product (aqueous slag) The weight should not be less than 2/3 of the machine’s injection volume. Based on these requirements, Ramada has developed a small and medium series of PET plasticizing systems in recent years. The clamping force is selected to be greater than 6300t/m2.


3, mold and gate design Pet Preform are generally formed by hot runner mold, between the mold and the injection molding machine template should have a heat insulation board, the thickness of about 12mm, and the insulation board must withstand high pressure. Exhaust gas must be sufficient to avoid local overheating or chipping, but the depth of the exhaust port should not exceed 0.03mm, otherwise it will easily produce flash.


4, the melting temperature can be measured by the air-launch method. Between 270 and 295 ° C, the enhanced grade GF-PET can be set to 290-315 ° C and the like.


5, the injection speed is generally faster, to prevent premature coagulation during injection. But too fast, the high shear rate makes the material brittle. The shot is usually completed in 4 seconds.


6, the lower the back pressure, the better, so as not to wear. Generally no more than 100bar. Usually no need to use.


7. Do not use excessive residence time for the residence time to prevent molecular weight from falling. Try to avoid temperatures above 300 °C. If the shutdown is less than 15 minutes. Only need to be air-blasted; if it is more than 15 minutes, clean it with viscosity PE and reduce the temperature of the barrel to PE temperature until it is turned on again.

China Pet Bottle With Good Reputation

Posted by nicolepreform on Feb 28, 2019 in News

In recent years, China’s medicinal Pet Preform packaging has developed rapidly. Medicinal PET bottles have the characteristics of light weight, no damage, health, etc., plus special requirements for pharmaceutical packaging. At present, pharmaceutical tablets, capsules and packaging have gradually realized “PET” generation “glass”.

The dose of PET bottles produced, if used improperly, the migration of trace elements will change the medicinal efficacy of the drug, and even taking drugs may be life-threatening. Drugs are a special commodity, and the medicinal PET bottle manufacturers they produce must be strictly controlled from every stage of production to meet the relevant requirements of health and compliance with “GMP”, and also have relevant laws and regulations, such as “People’s Republic of China”. Chinese Pharmacopoeia “Good People’s Republic of China Drug Administration Law” “Good Manufacturing Practices” “Pharmaceutical Packaging Management Measures” and related pharmaceutical PET bottles standards and requirements. At present, most pharmaceutical PET bottles, capsules, pharmaceutical packaging, so the production of PET bottles must ensure that pharmaceutical tablets, capsules are difficult to be deteriorated by moisture, heat-resistant melting, explosion, not easy to change color, when exposed to light, decomposition, Oxidation and pollution.

PET bottles are available in high-density polyethylene bottles (HDPE), polypropylene bottles (PP), polycarbonate bottles (PC), and polyester bottles (PET). In the early 1990s, a naphthalenedicarboxylic acid appeared. Ethylene glycol (PEN) PET bottles are better than PET, high strength, heat resistance, UV radiation resistance, high carbon dioxide gas and oxygen barrier properties, good chemical resistance, and are excellent materials for medicinal PET bottles.

Since there are many medicinal PET bottle sizes, colors and shapes, there are several main selection criteria:

1. Cap seal, water vapor permeability. Air tightness and moisture permeability play a vital role in the stability of charging

2. PET bottle product quality standards. Product quality analysis is performed from the manufacturer’s product quality standards to determine if it is desirable. Pharmaceutical PET bottle enterprises should set corporate standards higher than national standards, and industry standards are more stringent.

3. Select the main raw material of PET bottle, additive formula: The product standard of solid PET bottle is the applicable rule of main raw material, and must comply with non-toxic, no odor, etc., because there are many main raw materials, which need to be selected as raw materials. Overall performance, tablets generally use high-density polyethylene, polypropylene bottles, such as PET bottles can be used for transparency, better PEN bottle barrier properties, generally used in liquid pharmaceutical dosage forms of polypropylene or polyethylene bottle esters as the main raw material Made of materials.

4. PET bottle stability and compatibility. The use of PET bottles, especially drugs, using new PET bottles (or new materials, new processes) should be packed with advanced drug testing to check the stability and charge of the PET bottle with drug compatibility. Drug PET bottles interpenetrate, dissolve, adsorb, chemically react, and denature can be determined by scientific testing.

5. Quality assurance system. Supplier audits have become an essential part of the purchase of PET bottles. After the approval, the factory can produce a comprehensive and correct assessment of the overall level of software and hardware facilities, technical equipment, and quality.
