Continuing efforts to evolve environmentally friendly plastic containers.
Since the development of sorting-compatible caps began in 1995, we have been sincerely addressing environmental issues without pause, including efforts in weight reduction, biodegradable resins, bioplastics, and obtaining ISO 14001 certification. 【Examples of Initiatives】 ■ Sorting-compatible caps ■ Spouts for pouches (volume reduction) ■ Development of containers using biodegradable resins and bio-based materials ■ Obtaining ISO 14001 certification
Perfectly drained!
1. At the end of pouring, it stops dripping perfectly. It has good drip-free performance, making it hygienic to use. 2. The pouring hole allows for easy dispensing of the desired amount. It is possible to adjust the quantity for small or medium amounts based on the angle of tilt while pouring. 3. The amount of resin has been reduced compared to conventional products.
Plastic crown considering the environment and safety (for one-sho bottles and others)
Our RePD crown and Re-PMcap have won the WorldStar 2023 award in the Material & Components category at ThaiStar 2022. In Thailand, metal caps are the mainstream for liquor bottles, and plastic caps are still not common, which is why the advantages of our plastic caps have been recognized. <Award Points> - User-friendly design: Compared to metal, our caps are softer and have no sharp edges, allowing for easy opening without injuring fingers. - Environmentally considerate design: Since no part of the cap remains on the bottle, it can be easily sorted for recycling. <Product Information> - RePD crown ... Compatible with: 1.8-liter bottle necks - Re-PMcap ... Compatible with: M neck (our standard) ★ PET bottles can also be used.
![[Precision Machining Case Study] Ink Cap (Made of PP)](https://image.mono.ipros.com/public/product/image/6ae/2000763721/IPROS91143246004741080428.png?w=280&h=280)
Strict quality requirements such as the absence of burrs in the screw part for attaching the plug, along with examples that meet all of them!
We would like to introduce a case study of processing a PP cap designed to be attached to a solvent ink tank. To prevent leakage, we ensure high precision and minimize burr generation, with a dimensional tolerance of ±0.02mm. There are particularly strict quality requirements for the screw section where the cap is attached, which must be free of burrs, and we meet all of these requirements. Additionally, our company manufactured this product by machining from a PP block for prototype purposes, but in the future, mass production through resin injection molding will be necessary. Therefore, we are also proposing shapes to improve the yield of injection molding. [Case Overview] ■ Name: Ink Cap (PP) ■ Material: PP ■ Dimensions: 20×15×55mm ■ Precision: ±0.02 ■ Features: Six-sided machining while minimizing burrs *For more details, please refer to the related link page or feel free to contact us.
Re-pelletizing is possible after the crushing and dissolution process! A case study that reduced disposal costs by approximately 700,000 yen per year.
We would like to introduce a case study on waste and cost reduction for manufacturers that generate plastic caps during the product yield and separation processes with other material containers. The company had concerns about wanting to increase the purchase price of plastic caps to reduce overall costs. In response, we proposed the valuable purchase of plastic caps. Plastic caps can be repelletized after going through crushing and melting processes. As a result, the monetization of plastic caps allowed for a 100% reduction in waste plastic disposal costs. 【Case Study】 ■ Target Customers: Manufacturers that generate plastic caps during the product yield and separation processes with other material containers. ■ Challenge: To increase the purchase price of plastic caps and reduce overall costs. ■ Effects: - A 100% reduction in waste plastic disposal costs through the monetization of plastic caps. - For a customer with a discharge volume of 15 tons/month: approximately 700,000 yen/year reduction in disposal costs. *For more details, please refer to the PDF document or feel free to contact us.
