The present invention provides a self-emulsification type emulsion exhibiting excellent adhesion to olefin-based base materials such as polyethylene and polypropylene without using an emulsifier. The self-emulsification type emulsion of the present invention comprises a tackifier and a modified polypropylene resin having an anionic functional group, and satisfies (1) and (2) given below: (1) the modified polypropylene resin having an anionic functional group is dispersed in water in the absence of an emulsifier, and (2) a dispersion particle comprising the modified polypropylene resin having an anionic functional group surrounds the tackifier.

The present invention relates to an adhesive comprising an anti-insect ingredient comprising a plant extract, wherein the plant extract comprises an extract of Cinnamomum cassia, an extract of Syzygium aromaticum and an extract of Artemisia capillaris and an adhesive ingredient comprising a binder. The adhesive is environment friendly and does not have any toxic ingredient on a human body and exhibit excellent and synergic anti-insect efficiency by using three plant extracts. Therefore, it is possible to control pests that may have an adverse effect on foods by applying the adhesive to a food package box.

Amorphous propylene-ethylene copolymers are described herein that can include high amounts of ethylene and exhibit desirable softening points and needle penetrations. The desirable combinations of softening points and needle penetrations in these propylene-ethylene copolymers allow them to have a broad operating window. Due their broad operating window, the propylene-ethylene copolymers can be utilized in a wide array of applications and products, including hot melt adhesives.
