Milliken's new absorber absorbs 95% of ultraviolet light for PET bottles

[China Packaging Network News] As PET bottles easily transmit light, ultraviolet light can break down these artificial colors and preservatives, and it is easy to negatively affect the appearance, appearance, color, taste, and nutritional value of the contents, as well as the storage, distribution, and retail of products. The display process is inconvenient. Milliken (Milliken) at this year's Interpack show how to provide UV protection for PET bottles with additives.

The sorbent provides effective UV filtration and absorption to protect the contents while maintaining the permeability of the packaging material, bringing real value to PET packaging!

Absorbs and filters 95% of ultraviolet rays

ClearShield Absorber filters ultraviolet rays up to 390 nm at 95% of the wavelengths. A very low dose can be used to achieve effective results, allowing brands to use more UV-sensitive natural fragrances and colorants in the packaging contents. Brand owners can ultimately reduce costs by reducing the amount of stabilizers and preservatives they need, as well as reducing the complexity of the formulation.

reduce manufacturing cost

ClearShield has been approved by the European Food Safety Authority (EFSA) for food contact applications and it overcomes the deficiencies of traditional technologies. ClearShield UV absorbers are easy to handle and measure, and can be added directly to PET without penetrating the beverage. Manufacturers of PET preforms can also simplify the process by using PET with ClearShield.

To achieve sustainable development

But the benefits of using ClearShield are much more than that. It also brings sustainable benefits. “For start-ups,” said Simon Bousquet, technical manager at Milliken. “The dose of ClearShield can be reduced by 20 compared to conventional UV absorbers. Times, and the final protective effect is the same. At the same time, brand owners do not have to worry about it will be like toxic chemicals with some traditional UV stabilizers, but also pollute the wastewater.”

In addition, Bousquet pointed out: “Better content protection and extended shelf life help reduce product waste. With ClearShield, brands can continue to use natural, un-tinted PET, avoiding dark or colored containers. Packaging, he explained. "When those opaque and colored PET materials are recycled, they will make the recycling stream darker, making recycling more difficult and reducing the value of recycled products."

The European Plastics Recycling Association (PRE) headquartered in Brussels has also sounded the alarm: The number of colored PET bottles (bags) is gradually increasing, which will pose a danger to the future recycling of PET. PRE further pointed out that once the PET bottles are collected and sorted, these colored PET bottles need to be re-sorted. Once the recycle bins sell these colored PET bottles, they will be recycled and the recycled materials will be dyed black or gray. The value of use will also be greatly reduced.
