    摘要： The invention relates to a film extrusion die (1) for producing a single-layer or multilayer blown film. Said film extrusion die (1) comprises at least one melt gap (4) for forming a film layer, said melt gap (4) being formed between two boundary walls (5, 6). At least one melt line (22) opens into the melt gap (4) and becomes a first melt duct (4) within the melt gap (4), said melt duct (4) being formed by recesses (3, 7) in the two boundary walls (5, 6) of the melt gap (4) in at least one sub-section (11, 12, 13, 14) of the extension of the at least one first melt duct (10). The melt duct (10) distributes the melt in the melt gap (4) while tapering in the direction of travel of the melt (4) and merging entirely with the melt gap (4) in the end region (14) thereof (10). The novelty and inventiveness is considered to lie in the fact that in one of its sections (11, 12, 13, 14), the at least one first melt duct (10) is formed exclusively by recesses (3, 7) in one of its two boundary walls (5, 6).

    摘要： A film blowing machine rotary die head for starch biodegradation material comprises a core die part and an external body part which are mounted coaxially. The core die part comprises a spiral core die (22) which is sheathed on a central shaft (15) and a rotation core die (20) which is fixed at the upper end of the central shaft (15); the spiral core die (22) and the rotation core die (20) are attached to each other; the central shaft (15) is driven by a motor (2) so as to drive the rotation core die (20) to rotate correspondingly to the spiral core die (22). The external body part comprises an internal die sleeve (21), an external die sleeve (19) and a mouth die sleeve (23). The internal die sleeve (21), the mouth die sleeve (23), the spiral core die (22) and the rotation core die (20) together form a flowing and forming passage.
