摘要： A process for producing a container covered with a cylindrical heat shrinking film comprises preparing a continuous double layer sheet of a heat shrinking film by folding a continuous single layer sheet (22) supplied from a roll (21), sealing the open side of the continuous double layer sheet by heat, cutting the continuous double layer sheet to form a cylindrical heat shrinking film (1) having two open ends, disposing the cylindrical heat shrinking film around periphery of a container in an upright condition after moving past outside of floats (3,4), cutting and sealing an upper part of the film by heat to a shape of an arc (11) without removing the film from the container to form a heat shrinking bag film, pulling down the film until the sealed part is brought into contact with top of the container, allowing a lower part of the film to shrink by partial heating to bring the heated part tightly into contact with bottom of the container, and heating the whole film to bring approximately the whole film tightly in contact with the whole container while the container is kept in the upright condition. An apparatus for the process is also disclosed. A packaging line can be remarkably improved because the cylindrical heat shrinking film can be produced in the line. Shrinking ratio of the film can be decreased because a film of a size close to the container can be easily used. Appearance of the product container can be kept the same on all sides because the container can be transferred in an upright condition. Deformation of characters and patterns printed on the film can be avoided. Therefore, a container covered with a heat shrinking film of beautiful appearance can be produced efficiently.
