BioCor is a completely new plant-based biomass vaporization rust inhibitor that is produced by combining saturated fatty acids extracted from coconuts with cranberries and milk, taking into consideration the impact on the environment and human health. It is effective for both ferrous and non-ferrous metals, demonstrating high rust prevention capabilities. The antistatic agent used does not bleed (leach) and features a new mechanism of donor-acceptor type antistatic agent that maintains a long-lasting (semi-permanent) charge leakage effect on the surface and inside of the resin.

【No additive bleed-out】 In general poly bags, additives are added to improve productivity and bag-making suitability, but by using additive-free LDPE, it is possible to avoid additives. 【No additive adhesion to contents】 Since it is made from additive-free raw materials, there is no additive bleed-out on the outer and inner surfaces of the bag (the product contact surface), so there is no worry about additive particles adhering to the contents during filling or packaging. 【Optimal for general environmental usage levels】 This product is ideal for customers who are not using clean rooms but are concerned about particles, and find clean bags to be too costly.

• Packaging Bags

Clean gloves are made from materials like latex, which have poor breathability, leading to issues such as "stickiness and discomfort" and "difficulty in removing the gloves" when worn for long periods due to sweating. The clean inner gloves are specially designed inner gloves that solve these problems associated with clean gloves. The material used is a special long fiber that was originally utilized as a wiping cloth, applied to the inner gloves, providing excellent moisture absorption capabilities. It effectively absorbs sweat and significantly improves the operator's work efficiency. Additionally, it is highly durable and offers excellent cost performance, capable of withstanding 30 cleanings.

• Chemicals

In a normal state, molecular compounds that are bonded by cloning forces undergo charge transfer transitions under the influence of static electricity, leading to a sequential initiation of charge leakage as they instantaneously transform into ion pair structures. Among polymer materials that are insulators, some tend to become positively charged while others tend to become negatively charged. However, films incorporating donor-acceptor modified (molecular compound type antistatic agents) exhibit a unique and highly useful antistatic mechanism. Regardless of the type of charge generated, as soon as it occurs, one ion structure of the antistatic agent in the state of charge transfer transition neutralizes the charge, while the other ion structure facilitates hole diffusion or electron diffusion.

The ultraviolet (UV) cut clean standard bag is a clean polyethylene bag that cuts the transmission of ultraviolet rays, which promote the deterioration of the packaged items. In cleanroom-related packaging, there are many non-packaged items that are very sensitive to ultraviolet rays. Our "UV Cut Clean Standard Bag" is a groundbreaking ultra-clean type UV cut bag that cuts 99% of wavelengths below 385mm, which promote UV deterioration. Additionally, this UV cut clean bag is not made with the organic ultraviolet absorbers commonly blended into most UV cut types, so there is no bleeding (aggregation or powdering) of the UV cut agents to the film surface over time, eliminating concerns about particle generation, making it safe for use in cleanrooms. It is packaged in a convenient size with a small quantity, making it an ideal product for customers with lower usage needs. Of course, it is a standard stock item, so immediate delivery is possible.

The Zerast film contains Zerast components blended into polyethylene film, which gradually sublimate (vaporize) at room temperature and dissolve in the moisture of the atmosphere. The dissolved Zerast components suppress the imbalanced potential that forms on metal surfaces, inhibiting electrochemical reactions and preventing rust. Therefore, while the metal is wrapped in the Zerast film, the rust prevention effect is continuously sustained, protecting important products from rust. Additionally, this film complies with the Food Sanitation Act, Ministry of Health, Labour and Welfare Notification No. 20, "Standards for Synthetic Resin Utensils or Containers and Packaging Mainly Composed of Polyethylene and Polypropylene," as well as RoHS designated substances, allowing for safe use. There are three types available to match the metal material: for iron, for non-ferrous metals, and for both iron and non-ferrous metals, with standard products also available.

Traditionally, polyethylene bags (poly bags) have been made to order in terms of thickness, width, and length. While custom production allows for sizes that meet customer specifications, it typically involves long lead times and minimum production lots of several thousand pieces (which varies by size). As a result, customers who only use a few hundred bags a year may take several years to use up a single lot. If they become long-term inventory, the quality will inevitably decline, which goes against the demand for quality improvement in today's market. Our company has standardized large poly bags, which are typically less available as standard products. We also have an immediate delivery system in place, so please feel free to take advantage of this.
