Triangle colophony bag

The utility model discloses a triangular pine resin bag, which comprises a triangular main body, wherein the triangular main body is formed by a strip-shaped film which is folded into a quadrate with the folded edge of one surface treated by heat sealing; and the corners at both sides of the other surface not treated by heat sealing are folded outwards and are fixed to form bag ears. The triangular pine resin bag which is made of plastic film has the advantages of less material consumption and low cost; moreover, the bag can be nailed by a bamboo nail so as to be fixed on a pine tree, which ensures that the bag is easy to install; in addition, the bag is in the shape of a cone after pine resin is filled, and a user just needs to press the bottom of the triangular main body to completely strip down pine resin during receiving pine resin; therefore, the bag is very convenient for use.
