Pronto a utilizar, para um funcionamento sem problemas da embalagem automatizada<\/span><\/h1>\n

Que produto \u00e9 este?<\/span><\/h2>\n

Sacos em rolo com abertura pr\u00e9-fabricada<\/span><\/strong>, como o pr\u00f3prio nome indica \u2014 sacos de embalagem cuja abertura j\u00e1 se encontra pr\u00e9-aberta e que s\u00e3o fornecidos em bobinas cont\u00ednuas.<\/span><\/p>\n

Em resumo: a abertura de cada saco separa-se naturalmente, sem necessidade de amassar nem de soprar; basta peg\u00e1-lo e est\u00e1 pronto a usar. V\u00e1rios sacos s\u00e3o ligados em s\u00e9rie, formando um rolo, e carregados diretamente na m\u00e1quina de embalagem autom\u00e1tica. A m\u00e1quina puxa automaticamente o saco, abre-o com facilidade, enche-o com o produto, sela-o e expele-o \u2014 tudo de uma s\u00f3 vez.<\/span><\/p>\n

Os desafios com que poder\u00e1 estar a deparar-se<\/span><\/h2>\n

Problema n.\u00ba 1: A m\u00e1quina fica frequentemente com o saco encravado?<\/span><\/strong><\/p>\n

A abertura dos sacos comuns fica colada, o que dificulta a sua abertura est\u00e1vel pela m\u00e1quina, levando \u00e0 passagem de sacos vazios e \u00e0 paragem do equipamento, obrigando os trabalhadores a permanecerem constantemente de prontid\u00e3o ao lado da m\u00e1quina para resolver a avaria.<\/span><\/p>\n

Solu\u00e7\u00f5es para sacos em bobina com abertura pr\u00e9-formada<\/span><\/strong>: A abertura do saco j\u00e1 se encontra pr\u00e9-separada, pelo que o mecanismo de abertura da m\u00e1quina apenas necessita de uma ligeira assist\u00eancia para a abrir sem dificuldades. Cada saco passa de forma fluida e sequencial, com um tempo de paragem praticamente nulo.<\/span><\/p>\n

Problema n.\u00ba 2: \u00c9 preciso passar meia hora a reajustar a m\u00e1quina sempre que se troca um rolo de sacos?<\/span><\/strong><\/p>\n

Existem diferen\u00e7as no material e na espessura entre alguns lotes de sacos, o que obriga a uma recalibra\u00e7\u00e3o demorada dos par\u00e2metros do equipamento sempre que se troca o rolo.<\/span><\/p>\n

Solu\u00e7\u00f5es para sacos em bobina com abertura pr\u00e9-formada<\/span><\/strong>: Controlamos rigorosamente as dimens\u00f5es e a espessura de cada lote de produtos, garantindo uma qualidade constante. Est\u00e3o prontos a utilizar assim que s\u00e3o colocados na m\u00e1quina, sem necessidade de ajustes repetidos.<\/span><\/p>\n

Problema n.\u00ba 3: Preocupa-se com o desalinhamento dos c\u00f3digos QR ou dos motivos impressos?<\/span><\/strong><\/p>\n

Os sacos comuns podem deslocar-se ao serem transportados para a posi\u00e7\u00e3o de selagem, o que pode causar instabilidade na posi\u00e7\u00e3o de impress\u00e3o e desvios na selagem.<\/span><\/p>\n

Solu\u00e7\u00f5es para sacos em bobina com abertura pr\u00e9-formada<\/span><\/strong>: As dimens\u00f5es padronizadas, aliadas a um posicionamento preciso e ao sistema de rastreio de marcas de cor da m\u00e1quina, garantem que a posi\u00e7\u00e3o de impress\u00e3o em cada saco seja exata e consistente \u2014 todos os sacos no mesmo ponto, com precis\u00e3o em todas as vezes.<\/span><\/p>\n
