The present disclosure includes a process for making a package having a spout. The process includes heating a sealing area of a spout to a temperature at or above a melting point of the spout material; heating two multilayer structures around a portion of their peripheries to adhere the peripheries of sealant layers and form a partially sealed package having an opening; inserting the heated spout into the opening; and pressing opposing surfaces of the two multilayer structures around the spout to close the opening around the spout. Each multilayer structure includes a multilayer film having the sealant layer having at least 40% by weight of an ethylene-based polymer having a melting point below 112 C; an external layer including an ethylene-based polymer; and at least one intermediate layer disposed between the sealant layer and the external layer having a melting point at least 15 C higher than the sealant layer.

The present disclosure is appropriate for the technical field of packaging bag materials, and provides a full biodegradable high-barrier multi-layer composite material and a preparation method thereof as well as a packaging bag. The full biodegradable high-barrier multi-layer composite material comprises the following components: polylactic acid, terephthalic acid-adipic acid-butanediol copolyester, polyvinyl alcohol, polyurethane glue and starch carrageenan. Embodiments of the present disclosure provide the full biodegradable high-barrier multi-layer composite material which is obtained by using the terephthalic acid-adipic acid-butanediol copolyester as a degradable layer, using polyvinyl alcohol as a barrier layer and by composing the degradable layer with the barrier layer via polyurethane glue and starch carrageenan. Through the present disclosure, the problems, such as high oxygen permeation rate, poor barrier property and poor preservation degree, in the existing degraded film can be solved.

A sachet product that includes a biodegradable and/or home compostable sachet comprising a front film and a back film. In some examples, the front film and back film can include a middle layer that can contain paper with greater than 85% cellulose and an inner layer that can include different material, including but not limited to polyvinyl alcohol or polyhydroxylalkonate. The sachet can include a compartment adapted for storing a solid article where the solid article is an open cell foam. The open cell foam can include a water-soluble polymer and a surfactant.

A multilayer structure may include a polyethylene-based polymeric film comprising: a sealing layer; at least one middle layer; and a printing layer; and an external layer of ultraviolet or electron beam curable ink or varnish cured on the printing layer of the polyethylene-based polymeric substrate, wherein the multilayer structure has a thermal surface resistance such that when sealing bars are applied to the polyethylene-based polymeric film in cycles of sealing of no more than 2 seconds and at a temperature corresponding to the melting temperature of the polyethylene-based polymeric film, the sealing bars remain free of polymer.

The present specification relates to a method for manufacturing a polarizing plate and a polarizing plate. More particularly, the present specification relates to a method for manufacturing a polarizing plate locally having a depolarization region, and a polarizing plate.
