Definitions

  • This invention relates to containers and in particular containers used for transportation and storing chilled or frozen foods.
  • Chilled or frozen foods are commonly packed in insulated containers.
  • expanded foams are commonly used for providing insulation properties. The material however has low impact resistance and is not generally regarded as having sufficient structural integrity for packaging applications and as a result the foam is often protected by an outside box.
  • expanded foams are not approved for food contact applications and food within such containers consequently needs to be bagged or wrapped.
  • Metal foils are also used in packaging situations to provide insulation properties.
  • Metal foils present manufacturing problems, additional costs, physical properties are not compatible with machinery and standard processing techniques and consequently tend to be used only for smaller higher value items.
  • cardboard has good natural insulation qualities, which can be improved if a board is laminated, lamination also improving strength.
  • a method of forming a laminated material comprising the steps of corrugating a paper sheet and applying liner being a pre-made laminate of a paper backing and plastics film which is metallised on one side and corona treated on the other side.
  • the liner can include a bi-axially orientated polyester film which is metallised on one side and corona treated on the other side.
  • the liner can be preheated prior to its application to the paper sheet.
  • the liner can be heated by heating rollers and adhered to the paper sheet using a PVA adhesive with the metallised film of the liner outermost.
  • the liner can be heated by heating rollers and adhered to the paper sheet using a PVA adhesive with the metallised film of the liner innermost.
  • a laminating apparatus including means for feeding out a paper sheet and a liner to a set of corrugating rollers, the liner being a pre-formed paper laminate of paper and plastic film, and means for uniting the paper sheet and liner subsequent to the corrugation of the paper sheet.
  • the apparatus can include means for pre-heating the paper sheet and liner prior to same being fed to the corrugating rollers.
  • the apparatus may include means for feeding a second liner for lamination with the paper sheet.
  • the lamination of the paper sheet and liner with the second liner can be subsequent to the lamination of the paper sheet with the liner.
  • the lamination of the paper sheet and the liner with the second liner can be achieved with the assistance of a cluster of in-line pressure rollers.
  • the second liner can be a laminate of a plastics film and paper.
  • the paper used to form the laminate can be of various thicknesses and grades and within the definition of paper it is intended to include thicker semi-rigid paper sheets (cardboard) and recycled and composite sheet materials including cellulose fibres derived from a variety of materials.
  • a roll of paper 1 is threaded over a heating roller 2 and fed to corrugating rollers 6.
  • a liner material is fed from a roll 4 over a preheating roller 5 to the corrugating rollers 6 and laminated to one side of corrugated laminar 7 with the laminar being fed via rollers 8, 9 to nip rollers 10, where (optionally) a liner 11 from a roll 12 is fed via pre-heating roller 13 to the nip rollers 10 to provide a lining to the other side of the laminar.
  • a cluster of crushing and heating rollers 14 are positioned downstream of the nip rollers 10 through which the completed laminar is fed.
  • the paper 1 can be selected from a range of kraft and recycled papers.
  • the liner film has high gas barrier properties, high reflectivity to light and radiant heat, low permeability to gases and water vapour, it is attractive and decorative, exhibits good abrasion resistance and can be characterised or specified as:
  • the process of laminating the polyester laminate to any of the kraft liners is a reel to reel process using PVA adhesive, applied at normal room temperature at approximately 70 metres per minute.
  • Three reels of paper are delivered to the corrugator for loading one or two liners and one laminar.
  • the metallised side of the kraft liner can be threaded over the pre-heaters with the metallised side facing outwards or inwards (this avoids any likelihood of scuffing the metallised surface). Care must be taken to avoid scuffing if the inwards method is used.
  • An ideal corrugating speed is between 90 and 120 metres per minute.
  • the converting process (making of a finished box) cannot take place until 24 hours after corrugating. This time is necessary for the curing process i.e. cooling of the board and the moisture balance to finalise.

Abstract

La présente invention concerne un procédé de formation d'un matériau stratifié, comprenant les étapes consistant à onduler une feuille de papier (1), à appliquer une doublure (4) sur un ou sur les deux côtés de la feuille ondulée, la doublure étant un stratifié préformé constitué d'un support de papier et d'un film plastique métallisé sur un côté et traité par effet corona sur l'autre côté. L'invention concerne également un appareil de stratification utile dans le procédé ci-dessus, lequel appareil comporte des moyens d'alimentation d'une feuille de papier et d'une doublure en direction de rouleaux d'ondulation (6), la doublure étant constituée d'un stratifié préformé de papier et de film plastique, ainsi que des moyens pour unir la feuille de papier et la doublure, immédiatement après l'étape d'ondulation de la feuille de papier.
