Abstract
"FITA ADESIVA". Filmes úteis como forros de fita, e mais particularmente forros de filme de polipropileno biaxialmente estirado e fitas incluindo tais forros. Um filme de polipropileno biaxialmente estirado, quebradiço é proporcionado pela minimização da densidade de nucleação na folha vazada de polímero de polipropileno temperado e extrusado seguida pela maximização da taxa de crescimento esferulítico do polímero temperado resultante. A folha vazada assim formada é estirada em temperaturas maiores do que a normal nas subseq³entes etapas de orientação para a produção de filme de polipropileno biaxialmente estirado. Isto produz um filme mais quebradiço. A composição de polipropileno, a temperatura de extrusão, a temperatura do rolo de vazamento (isto é a temperatura de têmpera), e a temperatura de estiramento e outros parâmetros são selecionados de acordo com os ensinamentos aqui descritos de tal modo que o forro ou a fita resultantes possuam as seguintes propriedades preferidas, tomadas individualmente ou em qualquer combinação preferida: A) uma energia de tração na ruptura na MD de até cerca de 90 N-mm/mm^3 ^; B) um alongamento na ruptura na MD de pelo menos 70%. C) uma energia de punctura de até cerca de 130 N-mm; D) uma energia de dispensa de até cerca de 350 Ncm/cm^2 ^; E) quando dispensada sobre lâminas dispensadoras de metal ou de plástico serreadas comercialmente disponíveis, a borda serreada da fita ou do forro segue rigorosamente o contorno da lâmina dispensadora; e F) uma capacidade de ser rasgada à mão."SCOTCH TAPE". Films useful as tape liners, and more particularly biaxially stretched polypropylene film liners and tapes including such liners. A biaxially stretched, brittle polypropylene film is provided by minimizing nucleation density in the cast sheet of tempered and extruded polypropylene polymer followed by maximizing the spherulitic growth rate of the resulting tempered polymer. The cast sheet thus formed is drawn at higher than normal temperatures in the subsequent orientation steps for the production of biaxially drawn polypropylene film. This produces a more brittle movie. The polypropylene composition, the extrusion temperature, the casting roll temperature (i.e. the tempering temperature), and the drawing temperature and other parameters are selected according to the teachings described herein such that the liner or the The resulting tapes have the following preferred properties, taken individually or in any preferred combination: A) a tensile tensile energy at MD of up to about 90 N-mm / mm 3; B) an elongation at break in the MD of at least 70%. C) a puncture energy of up to about 130 N-mm; D) a dispensing energy of up to about 350 Ncm / cm 2; E) when dispensed onto commercially available serrated metal or plastic dispensing blades, the serrated edge of the tape or liner strictly follows the contour of the dispensing blade; and F) an ability to be torn by hand.
