Polyram Launches New Additives That Enable the Detection of Plastic Residues in Metal Detectors
A new concentrate makes it possible to detect plastic contaminants in food and can be detected in a lower percentage compared to competitors. The material is approved for contact with food, suitable for PE, PP, PA and acetal, convenient to combine with paints and can be worked as a concentrate or final compound
A game with magnetic color grains, was created to demonstrate as a magnetic capability.
Apart from the health damage that may be caused to the consumer, there is potential for great reputation damage here. In today’s era such publications can go viral quickly.
Biological infections, insects and more can be treated at a sanitary level with strict hygiene and cleanliness rules. Metal contaminants, screws or knives that accidentally get into the process are also easy to handle with metal detectors located on each packaging strip. But when it comes to plastic infections – there is already a challenge here. And why? The plastic is lightweight and unrecognizable. Therefore, its identification is more complex.
Conveyors, plastic boxes and sheets are used in many intermediate processes in food production. Wrapping meat in cooking processes in factories, storage vessels for ripening cheese and more. Earplugs, used by production workers, as well as plastic cables ties used to close food bags, are also common in the production surrounding. These may in the event of a malfunction reach the final consumer. For this very reason, blue-painted plastic aids are most often used. Because apart from a blue grape popsicle there are no food products with this color, the plastic pollution will stand out against the background of the product. The identification is done visually but is not certain, and faults occur. So, plastic scraps reach the final consumer and the damage increases.
Additives that can be detected by metal detectors – improving the quality control in the packaging line
In order to improve the quality control of manufacturing processes of these additives can be used Metallic (Metal detectable). These are added to a plastic product during its manufacturing process and allow the detection of plastic residues that are disconnected from it by a standard metal detector or X-Ray equipment that is in the production line.
The technology is not new but the additives available in the market have a number of disadvantages. First they require a particularly high dose in order to be well detected in the metal detectors. In addition, some tend to rust over time. Another disadvantage is the difficulty in combining them with color. These additives have a natural gray / brown color and the difficulty in combining them with other colors creates a product that is less eye-catching and is not always colored in the usual blue in the field. This makes it more difficult to work with a dual detection mechanism, both of metal detectors and of visual detection.
Polyram launches additives with increased sensitivity, with high detection capability in metal detectors
The Israeli Polyram, which specializes in the production of compounds and smart additives for a variety of industries, recognized this need in the market and decided to invest efforts in developing a more effective solution to the problem. The end result – RAMDETECT®, a magnetic concentrate / compound that can be combined in the production of plastics. The concentrate combines a number of distinct benefits. First, it is easily detectable and in lower percentages compared to other additives in the market. This reduces the percentage of its use and leads to financial savings. It can be detected in any metal detectors or X-Ray devices that already exist in the production line and does not require the purchase of detectors with increased sensitivity. In addition, the additive is not made of materials that can create rust and so this side effect is spared. The new additive can be pre-colored with a suitable color and thus can be used with a double detection mechanism in the production line – both detections using metal detectors, and visual detection.
Approved for contact with food – in concentrate or compound
The new product has food contact certificates, both from the FDA and from the EU authorities. The concentrate is available in four different polymer matrices suitable for PE, PP Nylon and Acetal – all four are common polymers in the industry of conveyors, boxes and plastic accessories.
In this industry it is common to work mostly with concentrates so that each customer can find the optimal dose for him. If necessary, the polymer has concentrating combination capabilities as well as a suitable color in the compound and the final matrix of the polymer from which the product is made. This way you can get a more balanced distribution of the concentrate in the matrix as well as operational simplicity and the consistency in performance.
Polymers in the field of application
Each application in the field requires an adjustment of the dosage to the capabilities of the manufacturer’s metal detectors according to the minimum size of plastic contamination you want to detect.
Polyram’s experts provide support to the company’s customers, advice, guidance and guidance.
From engineering polymers – to food applications
Polyram, which until now has focused on engineering polymers, continues to evolve in new directions. These solutions, which the company presents here for the first time, open the door to a new field of products for food and packaging applications, but not only. The company also reports interest in the product in other areas, such as the medical field. “Whenever a part with magnetic capabilities is needed – metals are used. These require complex painting processes. The possibility of replacing these parts with magnetic plastic can open up a whole new world of possibilities,” says Nathalie Borochovich, the company’s development manager.
Polyram says that many customers have already expressed interest in the product. “Customers in the market were thirsty for such a solution and some of them underwent a very expedited testing and approval process within a few weeks. The fast time indicates the importance of the solution and the advantages it has over other products in the market,” concludes Natalie.
