Milk bottle Swiss style PRELACTIA double barrier preform

[China Packaging Network News] Modern packaging, in addition to fulfilling some technical and economic functions, must also become an eye-catching advertising medium to stimulate purchase desire. For manufacturers of milk beverages, PRELACTIAPET preforms offer new possibilities ! Innovative bottle design allows them to stand out from the competition. This patented barrier preform also offers significant economic advantages with its two-layer construction.

At CHINAPLAS 2018 , Netstal will present a two-layer PRELACTIA barrier preform for milk bottles . PRERELAIA can be used to safely, economically and aesthetically package liquid dairy products with exceptional shelf life. The new cloud-based analysis application, AnalysiX, can help injection molding machines further increase efficiency.

Milk bottle maximum design freedom

Netstal will present an innovative packaging solution for PRELIACTIA for liquid dairy products at the International Rubber Show .

In the soft drink sector, brand owners have been using PET bottles for years of design freedom and have tried to stand out from the point of sale competition with unique and more unusual bottle shapes.

Since it is difficult to achieve this by HDPE or paper-packed milk, the advantages in this aspect of filling liquid dairy products have not been obvious so far. "PET preforms for the system PRELACTIA filling liquid dairy products has opened up new opportunities for a more prominent display of personalized bottle shape compared to competitors' sales director Netstal Asian region StefanMüller said.

Very few additives, but better photoresist properties

This patented two-layer barrier preform has an economic advantage over other packaging methods. In the overmolding method, an inner ash layer having a thickness of only 1 mm is first injected . The dark color ensures very good photoresist properties. "This is a dark brown glass milk bottle before made very similar. PRELACTIA block almost all the visible spectrum. Thus, such a bottle is very suitable for as long a shelf life of dairy products", said Müller. In the second production step, the previously injected blank was covered with a pure white outer layer of only 1.4 mm thick .

The PRELACTIA bottle has a thinner wall and a weight reduction of approximately 20% to 30%.

Coloring was carried out by adding a white pigment " titanium dioxide " . Unlike single-layer bottles, this method can reduce the titanium dioxide content from at least 10% to only 3% of the total weight . “ The market price of titanium dioxide is between seven and eight euros per kilogram. Therefore, the annual savings potential is also very impressive ", Müller said so.

Economical, durable pure PET milk bottle

Due to its ecological advantages, modern PET milk bottles may also replace obsolete bottles made of HDPE on the market for a long time . The price of PET raw materials is 30% cheaper than HDPE . Because the bottle wall of the PRELACTIA bottle is thinner and the weight is reduced by about 20% to 30%, it is more cost effective. “ Unlike extrusion blow molding, there is no significant material loss during injection molding. Water and energy consumption is greatly reduced. Material and resource savings bring rewards to brand owners, making PRELACTIA a sustainable solution. program ", Müller explains.

The thread is precisely defined by the injection molding process, and the bottle can be reliably sealed with a screw cap even after multiple opening, so no additional sealing is required with aluminum foil. PRELACTIA bottles are made of pure PET and are therefore recyclable in principle.

“ Despite the increasing market share, the recovery of colored PET has not yet been fully resolved in many countries . But as one of the largest countries in Europe, France says it can collect, separate and reuse milk made from colored PET . Bottle " , Müller stressed. In France, supermarket, the customer can fully purchased several years ago to use the PET bottle containing milk PRELACTIA.

Analytical applications using AnalytiX

"For our Chinese customers, industry 4.0 is a very important theme in the 'Plastics4.0' concept, Netstal developed innovative digital solutions, our customers can take to further improve production efficiency", Müller said, .

At CHINAPLAS 2018 , Netstal is the first to showcase AnalytiX, a new analytical application in Asia .

On CHINAPLAS 2018 , Netstal is the first to showcase its new analytical application , AnalysiX, in Asia . With cloud-based production monitoring, users can track the most important parameters of their machines online, anytime, anywhere. "Our customers will benefit from the automatic evaluation process and machine state. This saves a lot of time and increase staff productivity", Müller explains. With intelligent parameters on stability and productivity, the user can see the trend change or performance deviation of a single machine at a glance.

All data are stored in Switzerland

Data security is an important topic in Netstal . All information is hosted in the secure Netstal cloud in Switzerland and is not accessible to third parties. User management and access rights are fully in the hands of customers. AnalytiX is a prerequisite for using the injection molding machine equipped with "iOTReady Package".

It consists of an NRS connection module (Netstal remote support ) and a Euromap 15 interface. The network connection of the machine can be wired (LAN) or wireless (WIFI, 4G) . The base version of AnalytiX is free and is an app for iOS or Android. With paid subscriptions, you can flexibly adjust the range of features to your individual needs.
