Definitions

• the present disclosure generally relates to flexible packages and more particularly, to a flexible laminate tube for packing products.
• Various types of the flexible tubes are widely known for packaging several kinds of products, such as liquid products, semi solid products and the like, so that the products may reach to the consumers. All such flexible tubes may also include imprinted information, such as packed products' details, brand names, logo, trademark, manufacturing date, expiry date, batch number and/or any other general information, for facilitating the consumers to identify desired products in the market.
• Such flexible tubes may include the imprinted information either on an exterior surface or on an inner layer, depending upon the kind of the flexible tubes. For example, if a flexible tube is made by extrusion process, it will necessarily be imprinted on the exterior surface thereof. Such imprinting is done by surface printing or pasting preprinted stickers after the flexible tube or body thereof has been made. T e imprinted information on such flexible tubes may generally not be stable and get peeled, scratched, blurred or hazy in handling, transportation, usages, rubbing and the like.
• the flexible tubes including imprinted information on the inner layer thereof are used.
• the flexible tubes including imprinted information on the inner layer thereof are generally formed by multilayer polymeric laminates.
• the imprinted information is reverse printed on a transparent polymeric film and pasted over other polymeric film(s) to produce the laminates.
• Such laminates may be utilized for producing the flexible laminate tubes by a overlapping their opposite edges and sealing thereto via a heat sealing method.
• the heat sealing method is generally limited to only such laminates, where the inner and outer layers are heat sealable with each other.
• Other sealing methods such as hot melt extrusion sealing method may in many instances, melts the laminates and results in de- lamination.
• one edge of the laminate is generally exposed to the product packaged in the tube. Certain products when is in constant touch with the imposed edge of the laminate, result in de-lamination of various layers of the laminate. Such de- lamination may also blur or haze the imprinted information.
