Why EVOH Material Used In Sunscreen Bottle Packaging?

What is EVOH material?

Ethylene Vinyl Alcohol (EVOH) is a copolymer known for its excellent barrier properties which has been the most widely used high-barrier material. In addition to the non-stretch type, there are biaxially oriented aluminum vapor-coated and adhesive-coated film types and heat-resistant biaxially oriented film types for aseptic packaging products. The barrier properties of EVOH depend on the ethylene content, and in general, when the content of ethylene increases, the gas barrier decreases, but it is easy to process.

EVOH exhibits outstanding gas barrier properties and exceptional processability, alongside transparency, gloss, mechanical strength, stretchability, abrasion resistance, cold resistance, and excellent surface durability.

In the field of packaging, EVOH is made of composite film intermediate barrier layer, used in all rigid and flexible packaging; in the food industry for aseptic packaging, hot cans, and cooking bags, packaging of dairy products, meat, juice cans, and spices; in the non-food aspects, used for packaging of solvents, pesticides, chemicals, air conditioning structural components, gasoline drum lining, electronic components and so on. In food packaging, EVOH plastic containers can completely replace glass and metal containers, a number of domestic aquatic companies export seafood on the use of PE/EVOH/PA/RVOH/PE five-layer co-extruded film vacuum packaging. In accelerating the research of EVOH composite film at the same time, foreign countries are also studying the EVOH stretch orientation, and new EVOH film on the gas barrier performance for the existing high-performance non-stretch EVOH film 3 times. In addition, EVOH can also be used as a barrier material coated in other synthetic resin packaging materials, to enhance the effect of barrier properties.

Why is it good to use EVOH material for sunscreen plastic bottle packaging?

1. UV Protection

EVOH provides superior barrier protection against gases, such as oxygen, and moisture. This is crucial for sunscreen packaging, as it helps maintain the efficacy of the sunscreen's active ingredients by preventing oxidation and moisture ingress, which can degrade the product.

Sunscreens must shield their active components from UV rays, which can lead to deterioration. EVOH materials typically possess strong UV resistance characteristics, ensuring the sunscreen maintains efficacy and stability throughout its shelf life.

EVOH’s barrier properties help in preserving the fragrance, consistency, and color of the sunscreen, ensuring that the product remains appealing and effective throughout its shelf life.

2. Sustainability and Lightweight

 ◆  EVOH is resistant to a wide range of chemicals, including those found in sunscreens. This resilience guarantees that the packaging will not interact with the product, preserving both the packaging's integrity and the sunscreen's effectiveness.

 ◆  It can also be combined with other materials through co-extrusion to produce lightweight, multi-layer packaging. This reduces the overall amount of plastic used, contributing to more sustainable packaging solutions. The lightweight design of EVOH bottles also cuts down on transportation expenses and carbon emissions.

 ◆   Moreover, it seamlessly integrates with other plastics such as polyethylene (PE) or polypropylene (PP) in multi-layer configurations. This combination enhances the overall strength, durability, and flexibility of the sunscreen bottle while maintaining excellent barrier properties

 ◆  While EVOH itself is not widely recycled, its use in combination with recyclable materials like PE and PP can create packaging that is more easily recyclable. Advances in recycling technologies are also improving the recyclability of multi-layer packaging that includes EVOH.

 ◆  EVOH can be integrated into multi-layer configurations, decreasing the total plastic usage while maintaining exceptional barrier properties. This can lead to more sustainable packaging solutions with a lower environmental footprint.

This is the sunscreen bottle of a combination of HDPE and EVOH, FIVE LAYERS, capacity 30ml. it can be customized any color and printed any artwork.

Moreover, it used the recyclable PCR HDPE which it is better suited to recycling nowadays.

3. Transparency and Aesthetics

EVOH can be manufactured to be transparent, allowing consumers to see the product inside. This feature is appealing for packaging, as it can elevate the aesthetic appeal of the sunscreen bottle and instill consumer confidence by highlighting the product's quality.

EVOH plastic bottles are used in a variety of industries, including food and beverage, pharmaceuticals, cosmetics, and industrial applications. This adaptability makes EVOH a compelling option for manufacturers aiming to maintain product integrity across various industries.

Conclusion

EVOH plastic bottles provide a multitude of advantages, such as exceptional barrier properties, clarity, resistance to chemicals, and flexibility. These advantages make EVOH an excellent choice for packaging solutions that require high performance and product protection, contributing to longer shelf life, product safety, and consumer satisfaction.
