"BioPuchi" is a refreshing light green bubble sheet made from "green polyethylene" (from Braskem) derived from sugarcane byproducts. By incorporating approximately 15% green polyethylene, it is possible to reduce CO2 emissions by more than 5% compared to conventional materials. ■ SDGs 12 Responsible Production and Consumption It can significantly contribute to the prevention of global warming, of which CO2 is one of the contributing factors. 【Features】 ■ Refreshing light green color ■ More than 5% reduction in CO2 emissions ■ Significant contribution to the prevention of global warming, of which CO2 is one of the contributing factors ■ Green polyethylene is considered carbon neutral because the sugarcane used as the main raw material absorbs CO2 during its growth stage, resulting in zero CO2 emissions when incinerated as waste. *For more details, please refer to the PDF document or feel free to contact us.

【Features】 ■ Excellent thermal insulation and cooling properties ■ Superior insulation performance due to air bubbles ■ Light-blocking properties from aluminum film ■ Ease of processing Can be cut with scissors and heat-sealed with a sealer, allowing for the creation of bags. *For more details, please refer to the PDF document or feel free to contact us.

【Features】 ■Excellent Insulation Performance The independent bubble structure of the bubble sheet has low thermal conductivity and suppresses air convection. Additionally, the aluminum foil reflects radiant heat. ■High Radiant Heat Effect By reflecting heat, it improves heating and cooling efficiency, creating a comfortable environment that is cool in summer and warm in winter. It also contributes to savings on air conditioning costs and energy conservation. ■Workability It is very lightweight and compact, making transportation and installation at heights easy. A construction manual is also available. ■High Safety It is non-toxic and free of carcinogens, making it very safe. ■High Processability It can be easily cut with scissors or a cutter, improving work efficiency. It can be easily installed using various methods such as nailing, sewing, stapling, riveting, and taping. ■High Durability Made of aluminum and polyethylene, it has excellent corrosion resistance. *For more details, please refer to the PDF materials or feel free to contact us.*

**Features** ■ Insulation Performance It delays the transfer of heat, making it difficult for heat to pass through. Insulation is a common consideration for countering heat and cold. The air is independently sealed in bubble sheet (Puchipuchi), which has very high insulation performance. ■ Heat Shielding Performance It reflects infrared radiation (radiant heat), making it difficult for heat to pass through. Radiant heat transfers directly from a high-temperature solid surface to a low-temperature solid surface, regardless of the presence of gases like air. To prevent the transfer of radiant heat, "heat shielding," which reflects infrared radiation, is necessary rather than insulation. Aluminum has the property of reflecting this infrared radiation, which can mitigate the effects of radiant heat. ■ Workability It is very lightweight and compact, making transportation and installation at heights easy. A construction manual is also available. ■ High Processability It can be easily cut with scissors or a cutter, improving work efficiency. It can be easily installed using various methods such as nailing, stitching, stapling, riveting, and taping. ■ High Durability Made of aluminum and polyethylene, it has excellent corrosion resistance. *For more details, please refer to the PDF document or feel free to contact us.*

The Ministry of the Environment aims to double the recycling of plastics (use of recycled materials) by 2030 through its Plastic Resource Circulation Strategy. Our company has been manufacturing and selling bubble cushioning material, Puchipuchi(R), using recycled plastic raw materials for over 20 years. Based on our accumulated know-how, we can modify recycled materials and propose and sell recycled materials tailored to our customers' specifications. *We can also propose raw materials with specifications not listed in the catalog. Please feel free to contact us if you are considering the use of recycled materials or are looking for specific recycled materials. We can also propose recycled materials certified by the Global Recycled Standard (GRS).

This product consists of bubble wrap (Puchipuchi(R)) with aluminum foil laminated on both sides. 【Features】 ■ It has strong alkali resistance due to the anti-corrosion coating. It is suitable for use in "livestock barns," which are easily affected by ammonia. ■ Compared to conventional products, the thickness of the bubbles has been reduced, improving storage and transportation efficiency. ■ Compared to conventional products, the thickness of the aluminum has been increased, enhancing strength. ■ It possesses anti-corrosion coating performance while having a high infrared reflectivity (approximately 90%). ■ Heat insulation performance It reflects infrared (radiant heat), making it difficult for heat to transfer. Aluminum has the property of reflecting this infrared, which can suppress the effects of radiant heat. ■ Workability It is very lightweight and compact, making it easy to transport and install at heights. A construction manual is also available. ■ High processability It can be easily cut with scissors or a cutter, improving work efficiency. It can be easily installed using various methods such as nailing, sewing, stapling, riveting, and taping. *For more details, please refer to the PDF document or feel free to contact us.
