Asahi Plastics Co.

What Asahi Plastics Co. does

Asahi Plastics Co. (朝日樹脂工業株式会社) is a Japanese polyethylene film manufacturer founded in 1969 in Chiba Prefecture and headquartered in Tokyo (Taito-ku) since October 2024, with core manufacturing operations in Hitachiomiya City, Ibaraki Prefecture. The company produces HDPE and LLDPE films across thicknesses of 10μ to 140μ using inflation molding and T-die cast extrusion, supported by 26 inflation machines (4 with 1-color inline gravure printers) and 2 T-die machines, with downstream heat-seal bag-making capability at approximately 200°C.

Its product portfolio is split between standardized catalog items (the SuperWrap stretch film series — Green 18μ, Red 15μ, SuperLite 12μ — plus Standard Bag Fish, Standard Bag Meat, Sansanpoli poly bags, and Newspaper Film) and custom OEM products (HDPE/LLDPE raw stock in tube or flat film configurations with gravure printing and made-to-size bag making). Customers are Japanese industrial, logistics, and food processing buyers served via direct B2B sales; no customer logos or public pricing are disclosed.

Asahi operates as a wholly-owned subsidiary of Shimojima Co., Ltd. (株式会社シモジマ) since December 2019, with representative director Yusuke Fujita (藤田祐介) and 70 million yen in registered capital. The company has consolidated all manufacturing into its Ibaraki site following the 2009 merger with its former subsidiary, and its stated differentiators are small-lot OEM flexibility, short lead times, and environmental initiatives targeting CO2 and greenhouse gas reduction in production. No revenue, headcount, or funding history beyond the 2011 capital increase is publicly disclosed.
