 | |
| POLYSTAR has installed more than 300 sets of its Double Head Plastic film processing line in many leading T-shirt bag makers' factory in many countries. Two head film blowing machine In the Double Head Plastic film processing line, 1 die head can reach much higher output with a bigger extruder (such as 65mm or 75mm in diameter) even when producing smaller width film. It is especially effective for T-shirt bag makers who are looking for machine with higher output but lower cost. High production capacity Comparing to extruders with a single die head, the Two head film blowing machine can achieve higher production capacity when producing film roll that are small in width, as the high extrusion output is dispersed into two separate channels of the die heads instead of one. | |
 |  |
| Twin head for producing different film width The Double Head Plastic film processing line also allows producers to switch between HDPE and LDPE production as well as producing different film width on the same machine on each winder simultaneously. Special screw design A special screw design is used to provide good mixing and stable output for both HDPE and LDPE material. Bimetallic treatment is applied to process a higher percentage of recycled material and CaCO3 compound. POLYSTAR uses Siemens/ABB energy saving motors for the extruders which can reduce energy consumption up to 5%. | |

| Mexican shopping bag producer installed 13th POLYSTAR | |
| The Jalisco-based producer is producing 3,500 tons of plastic bags per month at the moment and aims to expand to 5,000 tons in the next 1.5 year with its plan to install more POLYSTAR machines. Both single die head (for making up to 1400mm in lay-flat) and twin die head (for making especially small sized bags) have been acquired for different products. The Double Head Plastic film processing line offers an economic alternative and has a much faster return on investment comparing to a blown film machine installed with internal bubble cooling system (IBC). In the Energy Saving Twin Head Blown Film System, 1 die head can reach much higher output with a bigger extruder (such as a 75mm in diameter) even when producing smaller width film. It is especially effective for T-shirt and market bag makers who are looking for machine with higher output, consistent quality but lower cost. This type of Double Head Plastic film processing line is most suitable for virgin (and in-house recycled) material (CaCO3 can be added). Comparing to extruders with a single die head, the twin die extruders can achieve higher production capacity when producing film roll that are small in width, as the high extrusion output is dispersed into two separate channels of the die heads instead of one. For T-shirt bag production from 350~750mm in width, the output for HDPE can range from 110 ~ 160 kg/hr with the DM75 model Double Head Plastic film processing line. The Double Head Plastic film processing line also allows producers to switch between HDPE and LDPE production as well as producing different film width on the same machine on each winder simultaneously. A special screw design is used to provide good mixing and stable output for both HDPE and LDPE material. | |

| Vietnam – setting new standards for standard blown film machines | |
| The Vietnamese plastic sector has grown significantly in the past 5 years thanks to many unique advantages that the country has. The ability to produce lower cost yet good quality plastic products is ideal for export markets such as the US, Japan, Europe, Australia and Cambodia. The local market demand is also increasing in sectors such as live seafood packaging, industrial and agricultural film, in a country of large population of nearly 100 million. Since 2016, POLYSTAR has already been working with 42 producers in Vietnam and has installed 187 sets of blown film extruders for various applications such as general packaging (garbage bags, vegetable and fruit bags, shopping bags), seafood packaging and industrial packaging. Higher productivity. Lower operation cost. Another bag producer located in Ho Chi Minh city - Tam Sao, has been expanding from 300 tones per month to 800 per month thanks to its ability to produce good quality yet low cost plastic bags, which are now exported to Europe, Thailand and Cambodia. “Our goal is to expand to 1,500 tones per month, and we rely heavily on POLYSTAR blown film extruders to stay competitive in the market.” Mr. Ho, the owner of the company, has replaced all of its Chinese made blown film machines step by step with POLYSTAR extruders since early 2016. “We were surprised that a simple machine can make such a big difference in operation. “To be honest, we had doubts in the beginning to invest in more expensive machines when we saw the price, as the initial investment on machines was more than doubled from our previous machine suppliers,” but we are so happy afterwards that we made the right decision 4 years ago.” Mr. Ho is also satisfied that since having switched to POLYSTAR machines, he has been able to reduce operation and labor costs significantly. “When we produce the same product on a POLYSTAR twin head 55mm extruder, the output is almost doubled comparing to a similar spec machine we had before. We’ve saved so much factory space and operation cost, basically producing more with less numbers of machines and less operators.” Simple operation. Stable operation. A fifteen-year-old company, Minh Huy Long, who recently completed its new factory putting only POLYSTAR machines, says that simple and stable operation is the main reason why he has chosen POLYSTAR as his long-term partner for expansion. “In our past experience with other machines, we had to constantly go back and adjust on the settings as the production was not as stable. “More production waste was generated, and our operators could not manage multiple machines at one time,” Mr. Bai jokingly said, “with the POLYSTAR machines, they can just start, sit back, relax and watch.” “The POLYSTAR machines are always the first ones they start in early morning, so they can go work on other machines after that.” The stability of the blown film machines also ensures product stability of other machines involved in the production process, such as bag making and printing machines. The even thickness control on the POLYSTAR extruders make sure that the film rolls produced are well-prepared for the process that follow – it makes the bag making/converting and printing process much easier. “The bag making machines can seal better, and we have less defected products as a result,” Mr. Bai added, “when our customers are happy, we are happier.” New standards. New Thinking. The director of Vipaco, a well-known film producer located in Hanoi who has started using POLYSTAR in 2016, has witnessed the change in the market. “In the past, you could find maybe one or two companies using machine from Taiwan in the bag production market. Now you see POLYSTAR everywhere in Vietnam. “In a way,” said Mr. Tuan, who focuses on export markets for Japan and the US, “POLYSTAR has changed the entire market and industry in Vietnam, setting new standards for standard machines,” he added, “more and more producers start to understand why they should invest more for quality machines.” | |
