Netstal: Durable and Cost-Effective Milk Packaging and Industry 4.0

– PRELACTIA: durable and cost-effective PET barrier preform for liquid dairy products

– AnalytiX: an overview of injection molding products that can be produced at any time anywhere

At the International Rubber Exhibition (April 24th to 27th, Hall 2 Stand T01), Netstal, a manufacturer of injection molding machines in Switzerland, will be exhibiting double-layer PRELATINIA barrier preforms for milk bottles. It is possible to use PRELACTIA for safety and economy. And beautifully package liquid dairy products with exceptionally long shelf life. The new cloud-based analytical application AnaytiX can help the injection molding machine to further increase efficiency.

Maximum design freedom of milk bottles Swiss injection molding machine manufacturer Netstal will exhibit at the International Rubber Show an innovative packaging solution for liquid dairy products PRELACTIA. In addition to numerous technical functions, today's modern packaging must be one Attractive advertising media, and with purchasing incentives. In the field of soft drinks, brand owners have used PET bottles for years of outstanding design freedom and have tried to compete at the point of sale through unique and more unusual bottle shapes. It stands out. Because it is difficult to achieve this with HDPE or paper-packed milk, so far, the advantages in filling liquid dairy products are not obvious. 'Plastic preforms made of PET have opened up the filling of liquid dairy products. New opportunities have been shown to be even better than competitors' personalized bottle shapes," said Stefan Müller, regional sales director for Asia at Netstal.

The additives are few, but the photoresist properties are better. Compared with other packaging methods, this patented double-layer barrier preform has economic advantages. In the overmolding method, an inner ash with a thickness of only 1 mm is injected first. Layer. Dark colors ensure very good photoresist properties. 'This is very similar to the milk bottle made of dark brown glass before. PRELACTIA can block almost all visible spectrum. Therefore, this kind of bottle is very suitable for the longest shelf life. The dairy products', Müller said. In the second production step, the previously injected blanks were covered with a pure white outer layer with a thickness of only 1.4 mm. The color was added by adding the white pigment 'titanium dioxide'. Unlike single-layer bottles, this method can reduce the titanium dioxide content from at least 10% to just 3% of the total weight. 'The market price for titanium dioxide is between seven and eight euros per kilogram. Therefore, the annual savings potential is also It's very impressive," Müller said.

Economical, Durable Pure PET Milk Bottles Because of its ecological advantages, modern PET milk bottles may also replace the outdated bottles made of HDPE on the market for a long time. PET raw materials cost 30% less than HDPE. Because of the Prelactia bottles The bottle wall is thinner and the weight is reduced by about 20% to 30%, so it is more cost-effective. 'Unlike extrusion blow moulding, there is no significant material loss during injection moulding. The consumption of water and energy is greatly reduced. The savings of resources and resources are rewarded to the brand owners, making PRELA- TACTIA a sustainable solution,” explained Müller. The thread was defined precisely by the injection moulding process and can be used even after several openings. Reliably seal the bottle so no extra foil is needed for sealing.

PRELACTIA bottles are made of pure PET and therefore are, in principle, recyclable. 'Despite the fact that the market share is increasing, in fact, the recovery of colored PET has not been completely solved in many countries. However, as one of the largest countries in Europe, France Said that it is possible to collect, separate and reuse milk bottles made from colored PET, Müller stressed. In supermarkets in France, customers can buy milk pre-filled in bottles made of PET as early as several years ago.

AnalytiX: Reliable Networking of Unique Injection Molding in the Cloud

'Industry 4.0 is a very important topic for our Chinese customers. Under the 'Plastics 4.0' concept, Netstal has developed innovative digital solutions that our customers can use to further increase their production efficiency', Müller Said. At the International Rubber Exhibition in Shanghai, the Swiss company demonstrated for the first time in Asia the new analytical application AnalytiX. With cloud-based production monitoring, users can track their machine's most important parameters online anytime, anywhere. 'Our customers will Benefits from automatic assessment of process and machine conditions. This saves a great deal of time and increases the efficiency of the employees', Müller explains. With intelligent parameters of stability and productivity, the user can see the trend of a single machine at a glance. Change or performance deviation.

All data is stored in Switzerland

In Netstal, data security is an important topic. All information is hosted on the secure Netstal cloud in Switzerland and cannot be accessed by third parties. The distribution of user management and access rights is entirely in the hands of customers. The prerequisite for the use of AnalytiX is the injection molding machine. It is equipped with 'iOT Ready Package'. It consists of NRS connection module (Netstal remote support) and Euromap 15 interface. The machine's network connection can be wired (LAN) or wireless (WIFI, 4G). The basic version of AnalytiX is free, yes An application for iOS or Android. With paid subscription, the range of functions can be flexibly adjusted according to individual needs.
