Abstract: In a secondary battery, a cell pouch for a secondary battery according to the present invention comprises an inner resin layer, a barrier layer, and an outer resin layer, wherein the inner resin layer, the barrier layer, and the outer resin layer are sequentially laminated, wherein a content ratio of PER (Propylene Ethylene Rubber) in the inner resin layer is 10% or less. According to the present invention, the electrolyte peel strength of the secondary battery cell is improved to ensure excellence and reliability, as well as it is possible to use a cell pouch for a secondary battery with excellent conditions such as an electrolyte peeling strength of 1,000 (gf/15 mm) or more, due to the property, in which the electrolyte peel strength of the secondary battery cell is inversely proportional to the content ratio of PER in the inner resin layer and is proportional to the length of PER.

Abstract: Disclosed is an eco-friendly packaging. The eco-friendly packaging with an accommodation space is formed by bonding multilayer films, and the multilayer films each include a first layer including a base layer including oriented polypropylene, and a coating layer applied to the outer surface of the base layer by coating, and a second layer laminated on the inner surface of the base layer, the second layer including cast polypropylene.

Abstract: Disclosed are an eco-friendly container label and a method of manufacturing an eco-friendly container. The eco-friendly container label to be attached to a disposable container includes a first layer including a print layer, and a barrier layer stacked on one side of the print layer, a second layer including an adhesive layer formed of the same material as the print layer, the adhesive layer to be stacked on the surface of the disposable container, and an intermediate base layer stacked between the first layer and the second layer and configured to bond the adhesive layer and the print layer.

Abstract: The present inventive concept is a hyuntak transistor that can prevent a thermal runaway phenomenon and a low heat high efficiency constant current circuit using an auxiliary transistor capable of a high amplification and a constant current. The circuit may be applied to drive a LED and a motor.
