Ethylene-Vinyl Alcohol Copolymer EVOH K102

In the current competitive packaging market, how to improve product freshness, extend shelf life, and reduce transport losses through material selection has become the core concern for brand owners and processors. And the first step of material selection often determines the lower and upper limits of the product.

As a professional supplier of virgin plastic pellets, we recommend EVOH K102 pellets from Kuraray, Japan. This product has become a core material in multilayer co-extruded film structures due to its excellent gas barrier properties, excellent processing adaptability, and high transparency.Its molecular structure has been optimised by Kuraray over many years of iterative technology to ensure gas barrier properties while achieving excellent melt homogeneity and process stability, making it suitable for a wide range of demanding packaging scenarios such as food, medical and agricultural applications.

Why Choose EVOH K102 ?

1. Excellent gas barrier performance to prolong freshness

EVOH K102 has an extremely low oxygen transmission rate (OTR), which can effectively isolate oxygen, carbon dioxide and other gases from penetrating, thus significantly prolonging the shelf-life of perishable goods such as food and medicine. The high crystalline distribution control technology keeps the barrier performance stable in high humidity environment, which is an ideal alternative to the traditional PA6+PE structure.

2. Excellent processing performance, improve production efficiency

K102 has good melt flow and thermal stability, suitable for blown film, cast film, thermoforming and other processing methods. It has moderate melt index (190℃/2.8 g/10min, 210℃/6 g/10min), supports high speed multi-layer co-extrusion, especially suitable for 5-7-9 layer film structure design, with good melt adhesion, can be co-extruded with PE, PA, EAA, EMAA and other materials.

3. High transparency, both barrier and visual value

EVOH K102 achieves high barrier performance while still maintaining excellent transparency and gloss, especially for packaging scenarios that require ‘visual freshness’, such as refrigerated deli foods, ready-to-eat lunches, fresh-cut fruits, etc., to help the brand stand out on the shelf at a glance and enhances product trust and purchase conversion. It helps brands to stand out on the shelf and increase product trust and purchase conversion rate.

4. Green and recyclable, responding to the trend of environmental protection

K102 is a recyclable EVOH material, in line with the direction of sustainable packaging. Its low additive ratio (often used as an intermediate layer) has less impact on the recyclability of the overall packaging structure, which makes it easy for companies to fulfill their functional needs while practicing their environmental responsibility.

Industry Applications of EVOH K102

Breakthrough Progress and Practical Applications

1. Food Packaging: Extend freshness and reduce wastage

EVOH K102 has extremely low oxygen permeability and is widely used in the packaging of meat, cheese, and delicatessen foods, which effectively extends shelf life and helps brands reduce wastage in the cold chain and inventory.

2. Pharmaceutical packaging: guarding stability, ensuring efficacy

In demanding pharmaceutical packaging, K102 can block the penetration of oxygen and water vapor, and is widely used in vaccines, reagent bags and other products to enhance the overall safety of medicines.

3. Agricultural Packaging: Extend efficacy, improve efficiency

Applied to pesticide microencapsulation film, EVOH K102 helps to accurately control the release time of pesticides, improve crop utilization, and reduce resource loss.

4. Electronic packaging: Moisture and oxygen protection, safeguard precision components

Applied to high-end electronic product packaging, K102 can prevent moisture and oxidation erosion, prolonging the storage life of chips, modules, and other highly sensitive components.
