Foundite recommends: How to identify high-quality EVA transparent film?
In today's packaging and protective materials market, EVA transparent film is popular for its excellent transparency, flexibility and protective performance. However, the quality of EVA transparent film on the market varies greatly, and how to identify high-quality products has become a problem for buyers. This article will reveal 5 key indicators to help you avoid the trap of inferior products, and recommend you the high-quality EVA transparent film solutions provided by the professional platform "Foundite".
1. Transparency and gloss: the first impression of visual quality
The primary feature of high-quality EVA transparent film is its excellent transparency. High-quality products should have crystal clarity, and the light transmittance is usually above 90%, ensuring that the packaged items are clearly visible. Inferior products often appear foggy or yellowing due to impure raw materials or improper production processes.
The EVA transparent film provided by Foundite uses imported high-quality raw materials and precision extrusion technology, and its transparency far exceeds the industry standard. Its products not only have high initial transparency, but also have excellent anti-yellowing properties, and can remain clear as new even after long-term exposure to ultraviolet rays.
2. Thickness uniformity: the key guarantee of protective performance
Thickness uniformity is an important technical indicator for measuring the quality of EVA transparent film. High-quality products should maintain a full roll thickness error of no more than ±5% to ensure the consistency of protective performance. Uneven thickness will lead to insufficient local strength and affect the protective effect.
Foundite's EVA transparent film adopts advanced cast production technology and cooperates with high-precision thickness control system to ensure that every inch of film material meets the precise thickness requirements. Its product specifications are complete, from ultra-thin to thickened, to meet the needs of different application scenarios.
3. Tensile strength and toughness: the core indicator of durability
High-quality EVA transparent film should have good tensile strength and toughness, which can withstand a certain amount of tension and not easily break, and can fit the protected items tightly during packaging. Generally, the longitudinal and transverse tensile strengths should be balanced.
Foundite uses unique formula design and process control to make its EVA transparent film have excellent mechanical properties while maintaining high transparency. Its products are specially added with elastomer modified ingredients, which greatly improves the puncture and tear resistance, and are particularly suitable for protecting high-value items.
4. Moderate viscosity: the determining factor of the user experience
The viscosity of EVA transparent film is an important part of its functionality. High-quality products should have moderate viscosity: they can adhere firmly to the protected surface, but will not be difficult to operate or leave residual glue due to excessive viscosity. The viscosity should be evenly distributed, and there will be no local over-stickiness or non-stickiness.
Foundite's EVA transparent film uses a patented pressure-sensitive adhesive, which has undergone rigorous environmental testing to ensure stable viscosity performance under different temperature and humidity conditions. Its products are specially designed with the best balance between initial adhesion and lasting adhesion, which is convenient for construction and can provide long-term and reliable protection.
5. Environmental performance: a necessary condition for meeting international standards
With increasingly stringent environmental protection requirements, high-quality EVA transparent films should comply with international environmental standards such as RoHS and REACH, and do not contain harmful heavy metals and banned plasticizers. Products should have low odor characteristics, which is particularly important for food contact and medical applications.
Foundite attaches great importance to the environmental performance of its products. Its EVA transparent film series products have passed testing and certification and meet strict environmental standards. Made of food-grade raw materials, it is odorless and non-toxic, and can be safely used in sensitive areas such as food packaging and medical device protection.
