Description
МНОГОСЛОЙНЫЙ МАТЕРИАЛ С ЗАЩИТНЫМИ СВОЙСТВАМИ MULTILAYERED MATERIAL WITH PROTECTIVE PROPERTIES
ДЛЯ УПАКОВКИ ПРОДУКТОВ FOR PACKING PRODUCTS
Изобретение касается многослойного материала для использования в качестве упаковочного материала и способов его получения. The invention relates to a multilayer material for use as packaging material and methods for its preparation.
В настоящее время все большее распространение получает изготовление и сбыт контрафактных товаров и материалов, что представляет собой серьезную проблему как для потребителей, так и для производителей оригинальной продукции. Упаковку и внешний вид контрафакта часто невозможно отличить от оригинальных, что вводит в заблуждение потенциальных покупателей. В результате возникает целый ряд проблем: производитель оригинального продукта недополучает прибыль, потребитель покупает товар неизвестного происхождения и качества, что, соответственно, может повлиять на репутацию производителя. Низкое качество, которое в основном имеют поддельные изделия может повлечь представление соответствующих рекламаций, и тогда производитель должен будет доказать непричастность к попаданию такого товара на рынок. Исходя из вышеизложенного, очень желательно, чтобы продукт или его упаковка имели специальные защитные признаки, по которым можно было бы распознать их оригинальность. Currently, the manufacture and marketing of counterfeit goods and materials is becoming more widespread, which is a serious problem for both consumers and manufacturers of original products. The packaging and appearance of counterfeit products are often impossible to distinguish from the original, which is misleading to potential buyers. As a result, a number of problems arise: the manufacturer of the original product loses profit, the consumer buys goods of unknown origin and quality, which, accordingly, can affect the reputation of the manufacturer. Poor quality, which fake products generally have, can lead to the submission of relevant complaints, and then the manufacturer will have to prove that he is not involved in getting such a product on the market. Based on the foregoing, it is highly desirable that the product or its packaging have special protective features by which their originality could be recognized.
Много разнообразной продукции, например, пищевой, фармацевтической и химической, которая реализуются в упаковке, не дает покупателю возможности оценить товар по его внешнему виду. Поэтому уже сама упаковка должна иметь определенные обозначения, элементы, оттенки и т.д., которые будут подтверждать оригинальность изделия. A lot of diverse products, for example, food, pharmaceutical and chemical, which are sold in packaging, does not allow the buyer to evaluate the product by its appearance. Therefore, the packaging itself should have certain designations, elements, shades, etc., which will confirm the originality of the product.
Одним из самых распространенных методов защиты оригинальной продукции является нанесение на упаковку голограммных элементов. Например, известен ламинат с объемной голограммой (патент N° ЕР0949547), включающий субстрат, первый адгезивный слой, слой с объемной голограммой, второй адгезивный слой и поверхностную защитную пленку, при этом вещество, обеспечивающее передачу длины волны записи к слою с объемной голограммой, содержится в первом и/или втором адгезивном слое. Сам слой с объемной голограммой является светочувствительным материалом, который содержит полимерную матрицу, соединение, которое способное к фотополимеризации, инициатор
фотополимеризации, сенсибилизирующий пигмент и, в случае необходимости, пластификатор и поверхностно-активное вещество. В качестве субстрата могут использоваться пленка, бумага, металл и т.д. One of the most common methods of protecting original products is applying hologram elements to packaging. For example, a laminate with a volume hologram is known (patent N ° EP0949547), including a substrate, a first adhesive layer, a layer with a volume hologram, a second adhesive layer and a surface protective film, while a substance that provides the recording wavelength to the layer with a volume hologram is contained in the first and / or second adhesive layer. The volume hologram layer itself is a photosensitive material that contains a polymer matrix, a compound that is capable of photopolymerization, an initiator photopolymerization, a sensitizing pigment and, if necessary, a plasticizer and a surfactant. As a substrate, film, paper, metal, etc. can be used.
Недостатком голограммных элементов является то, что они требуют большого количества материалов и сложных технологических операций для своего изготовления, а соответственно влекут за собой значительные затраты времени и денег на производство. The disadvantage of hologram elements is that they require a large number of materials and complex technological operations for their manufacture, and accordingly entail a significant investment of time and money for production.
Ближайшим аналогом предложенного технического решения является термозварний многослойный материал (патент US N° 4048736), включающий внешний слой из прозрачного термостойкого полимера (в основном биаксиально ориентированную полипропиленовую пленку), напечатанный рисунок, слой с нанесенным красителем (в основном полиэтиленовую пленку) и промежуточный слой. Недостатком известного многослойного материала является недостаточная надежность защитных признаков (поскольку красители могут проходить из одного слоя в другой, а при контакте с продуктом - на продукт), необходимость выполнять дополнительную технологическую операцию печати перед процессом ламинирования, а также простота воспроизведения защитных признаков (поскольку для запечатывания одним цветом не требуется высокоспециализированного технологического оборудования). В основу заявленного изобретения поставлена задача задача - повысить надежность включения защитных признаков в материал и упростить его изготовление и снизить стоимость путем исключения дополнительной технологической операции печати перед процессом ламинирования. The closest analogue to the proposed technical solution is a thermoset multilayer material (patent US N ° 4048736), including an outer layer of a transparent heat-resistant polymer (mainly biaxially oriented polypropylene film), a printed pattern, a layer coated with a dye (mainly a polyethylene film) and an intermediate layer. A disadvantage of the known multilayer material is the insufficient reliability of the security features (since dyes can pass from one layer to another, and when it comes in contact with the product, onto the product), the need to perform an additional printing operation before the lamination process, as well as the simplicity of reproduction of security features (as for sealing one color does not require highly specialized technological equipment). The basis of the claimed invention the task is to increase the reliability of the inclusion of protective features in the material and to simplify its manufacture and reduce cost by eliminating the additional technological printing operation before the lamination process.
Поставленная задача решается созданием многослойного материала с защитными свойствами для упаковки продуктов, состоящего как минимум из двух слоев, соединенных с помощью слоев адгезива, в котором, согласно изобретению, по крайней мере один слой материала является прозрачным и/или полупрозрачным и а по крайней мере один слой адгезива содержит краситель или смесь красителей. The problem is solved by creating a multilayer material with protective properties for packaging products, consisting of at least two layers connected by adhesive layers, in which, according to the invention, at least one layer of material is transparent and / or translucent and at least one the adhesive layer contains a dye or a mixture of dyes.
При этом, слои многослойного материала могут быть выполнены из полипропилена, полиэтилентерефталата, полиэтилена, бумаги, металлической фольги, металлизированной пленки или подобных материалов.
При этом, адгезив представляет собой композицию на основе полиуретана. In this case, the layers of the multilayer material can be made of polypropylene, polyethylene terephthalate, polyethylene, paper, metal foil, metallized film or similar materials. In this case, the adhesive is a composition based on polyurethane.
При этом, краситель представляет собой композицию на основе нитроцеллюлозы . In this case, the dye is a composition based on nitrocellulose.
При этом, краситель или смесь красителей содержится в слое адгезива в количестве 1 -30 мас.%. In this case, the dye or mixture of dyes is contained in the adhesive layer in an amount of 1-30 wt.%.
Таким образом использование такого ламината, исключает возможность миграции цветных пигментов из материала, контактирующего с продуктом, позволяет исключить из технологического цикла изготовления материала дополнительную операцию печати, а также обеспечивается сложность воспроизведения защитных признаков, поскольку конкретный оттенок красителя сложно воспроизвести без специальных станций смешивания красителя. Thus, the use of such a laminate eliminates the possibility of migration of colored pigments from the material in contact with the product, eliminates the additional printing operation from the manufacturing cycle of the material, and it also makes it difficult to reproduce security features, since a specific dye shade is difficult to reproduce without special dye mixing stations.
