Do EVA sole flip flops have a strong smell when new?
As a supplier of EVA sole flip flops, I often encounter inquiries from customers regarding the potential smell of our products when they are brand - new. It's a valid concern, as many consumers are sensitive to odors, especially when it comes to items that will be in close contact with their feet. In this blog, I'll delve into the reasons behind any possible smell in new EVA sole flip flops, the factors that influence it, and what we do to minimize it.
Understanding EVA Material
Ethylene - Vinyl Acetate (EVA) is a copolymer widely used in the footwear industry, including flip flops. It's favored for its lightweight, flexible, and shock - absorbing properties. EVA is made by combining ethylene and vinyl acetate monomers through a polymerization process. During this manufacturing process, various chemicals are used, which can contribute to the initial smell of the product.
The raw materials used in EVA production, such as the vinyl acetate monomer, can have a distinct odor. Additionally, the additives and processing agents employed to enhance the properties of EVA, like plasticizers, stabilizers, and colorants, may also emit smells. These substances are necessary to ensure the durability, flexibility, and appearance of the flip flops, but they can be the source of the unwanted odor.
Factors Affecting the Smell
Several factors can influence the intensity of the smell in new EVA sole flip flops:
Manufacturing Process
The quality of the manufacturing process plays a crucial role. If the production facilities do not have proper ventilation or if the curing process is not carried out correctly, the chemicals may not fully dissipate, leading to a stronger smell. At our company, we adhere to strict manufacturing standards. Our production facilities are equipped with advanced ventilation systems to ensure that any volatile chemicals are removed during the production process. We also carefully control the curing time and temperature to allow the EVA to fully set and the odorous substances to evaporate.
Storage Conditions
The way the flip flops are stored can also affect the smell. If they are stored in a poorly ventilated area or in a confined space for an extended period, the odor can become more concentrated. We store our products in well - ventilated warehouses to prevent the accumulation of odors. Moreover, we ensure that the storage temperature and humidity are within the optimal range to maintain the quality of the EVA sole flip flops.
Quantity of Additives
The amount of additives used in the EVA formulation can impact the smell. Some manufacturers may use a higher quantity of additives to achieve certain properties, which can result in a stronger odor. We carefully balance the use of additives to ensure that the flip flops have the desired characteristics without excessive smell. Our R & D team is constantly working on optimizing the EVA formulation to reduce the reliance on odor - causing additives.
How to Minimize the Smell
If you purchase new EVA sole flip flops and notice a slight smell, there are several ways to minimize it:
Ventilation
Simply leaving the flip flops in a well - ventilated area for a few days can significantly reduce the smell. You can place them outdoors in a shaded area or near an open window. The fresh air will help to disperse the volatile chemicals.
Sunlight Exposure
A short period of sunlight exposure can also be beneficial. The UV rays can help to break down some of the odor - causing compounds. However, be careful not to expose the flip flops to direct sunlight for too long, as this may cause the EVA to degrade or change color.
Using Natural Deodorizers
You can place the flip flops in a plastic bag with a few pieces of activated charcoal or a slice of lemon. These natural deodorizers can absorb the odors. Leave them in the bag for a couple of days, and you'll notice a reduction in the smell.
Our Commitment as a Supplier
At our company, we understand the importance of providing products with minimal odor. We are committed to using high - quality raw materials and advanced manufacturing processes to reduce the smell of our EVA sole flip flops. Our quality control team conducts regular inspections to ensure that the products meet our strict odor standards.


We also offer a wide range of EVA sole flip flops, including Cork Slippers Women's, FOOTBED Slides, and Women Thick Platform Leather Slippers Summer Beach EVA Soft Sole. These products are not only stylish but also designed to have a minimal smell when new.
Conclusion
In conclusion, while it is possible for new EVA sole flip flops to have a slight smell due to the manufacturing process and the nature of the EVA material, the intensity of the smell can be minimized through proper manufacturing, storage, and after - purchase care. As a supplier, we are dedicated to providing our customers with high - quality EVA sole flip flops that have a minimal odor.
