Ishii Foods, TBM, and environmentally friendly material LIMEX were used.
Developed the world's first sealant film for food packaging.

~Functional properties equivalent to conventional ones, such as heat resistance and seal strength, adopted in chilled hamburgers scheduled to be released in 2024~

Ishii Foods Co., Ltd. (Headquarters: Funabashi City, Chiba Prefecture, Representative Director, President and Executive Officer: Tomoyasu Ishii, hereinafter referred to as "Ishii Foods"), which is producing products using additive-free cooking *1, and an environmental alternative to plastic and paper. TBM Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo, Representative Director and CEO: Nobuyoshi Yamasaki, hereinafter referred to as TBM), which develops, produces, and sells the considerate material "LIMEX," is the world's first*2 company to develop the material for chilled food packaging, etc. We are pleased to announce that we have successfully developed a sealant film for food packaging*3 using LIMEX that can be handled by It has been decided that hamburgers from Ishii Foods' "Local and Seasonal" series, which is scheduled to start selling from February 2024, will be used in hamburger steaks. It is scheduled to be used in hamburger with tomato sauce (cabbage roll style).

Background

In October 2019, Ishii Foods and TBM agreed to aim to reduce the environmental impact of both companies toward a sustainable society, and concluded a basic agreement to utilize the environmentally friendly material "LIMEX." After signing the agreement, the two companies have been developing food packaging (flexible packaging materials) using the environmentally friendly material LIMEX.

In addition to developing food packaging, Ishii Foods is also working on activities to promote the conservation of water and forest resources and the reduction of petroleum usage, and is considering adopting it in its main products, such as business cards for all employees and food trays for New Year's dishes. We adopted LIMEX products.

Features of sealant film for food packaging using the environmentally friendly material LIMEX

This product is suitable for food packaging containing the environmentally friendly material LIMEX (LIMEX Pellet) through collaboration in material design and processing technology with Idemitsu Unitech Co., Ltd. (Headquarters: Minato-ku, Tokyo, President and CEO: Hiroto Morikawa) We have realized a laminated film. This product is a sealant film that can be used as food packaging (flexible packaging) with superior environmental performance compared to conventional plastic packaging films.

Can reduce petroleum-based plastic usage by approximately 26% and greenhouse gas emissions including CO ₂ by approximately 24%.

Compared to current polyethylene sealant films, it is expected to reduce the amount of petroleum-based plastic used by approximately 26% and greenhouse gas emissions including CO ₂ by approximately 24% ^*.

^* Based on LCA (calculation of environmental impact from raw material procurement to disposal) by TBM. May vary depending on manufacturing conditions. These are reference values and are not guaranteed values.

Tear-openability Improved manual tearability

By using the environmentally friendly material LIMEX (LIMEX Pellet) in part of the film, it improves tear-opening properties after lamination, allowing you to open the package cleanly without using any force.

Compatible with oil-based foods, has functional properties comparable to conventional products such as heat resistance, seal strength, and impact resistance, and complies with the Food Sanitation Act.

It has heat resistance (up to 95℃ boiling), sealing strength, and impact resistance that can be used with oil-based foods, and after lamination, it has functional properties equivalent to conventional plastic packaging films. It also complies with the "Specifications and Standards for Foods, Additives, etc." (Ministry of Health and Welfare Notification No. 370, 1952) based on the Food Sanitation Act.
