Abstract
"SACO DE PAPEL MULTIFOLHADO ACOPLADO COM INVóLUCRO PLáSTICO ESTANQUE POR MEIO DE COSTURA". As embalagens atualmente utilizadas para transporte de produtos alimentícios em pó, tais como soro e leite em pó, especialmente aqueles destinados à exportação, são compostas por dois sacos distintos: um envoltório singelo de polietileno de baixa densidade que recebe o produto, com o qual ficará em contato, e um saco de papel multifolhado dentro do qual o envoltório plástico é introduzido antes ou depois do enchimento. Tais embalagens não possuem resistência mecânica suficiente nem oferecem protetividade adequada aos citados produtos, uma vez que a proteção conferida pelo envoltório plástico está limitada à ação contra líquidos. Nem esse envoltório nem as folhas de papel protegem o produto contra gases e vapores em geral e agentes externos de natureza similar, que podem contaminar o produto ou adulterar suas propriedades. Há ainda a dificuldade de manuseio do conjunto formado pelo produto inserido em duas embalagens em separado. O presente modelo de embalagem vem solucionar esses problemas, uma vez que combina as propriedades de proteção do papel kraft multifolhado com as de um invólucro estanque de plástico coextrudado de poliamida + polietileno linear de baixa densidade (PA + PELBD), o qual garante a adequada proteção contra gases e vapores. O acoplamento entre os invólucros de papel e o plástico é feito por costura, conferindo maior resistência ao conjunto."MULTI-FOLDED PAPER BAG COUPLED WITH SEAL-SEALED PLASTIC COVER". The packaging currently used for the transport of powdered food products such as whey and milk powder, especially for export, is made up of two separate bags: a simple low-density polyethylene wrapper that receives the product, with which it will be on contact, and a multi-sheet paper bag into which the plastic wrap is introduced before or after filling. Such packages do not have sufficient mechanical strength and do not offer adequate protection to these products, since the protection provided by the plastic wrapping is limited to the action against liquids. Neither this wrapper nor the sheets of paper protect the product against gases and vapors in general and external agents of a similar nature, which may contaminate the product or tamper with its properties. There is also the difficulty of handling the set formed by the product inserted in two separate packages. The present packaging model solves these problems by combining the protective properties of multi-ply kraft paper with that of a watertight polyamide + low density linear polyethylene (PA + PELBD) tight casing which ensures proper protection against gases and vapors. The coupling between the paper wrappers and the plastic is made by stitching, giving greater resistance to the set.
