EFFECT OF CORRUGATED CARDBOARD SHAPE ON THE PACKING DAMPING PROPERTIES
Rubrics: MECHANICS
Abstract and keywords
Abstract (English):
The present work objective is searching for such forms of the cardboard corrugation which could effectively absorb the impact load on a cardboard sheet, both vertical and horizontal. The re-search subject is the depreciation efficiency of the cardboard package with a cell and an alternative (with MS-profile) structure by the action of shock across and along the honeycomb. Meas-urement and comparation of the deformation rate, as well as the shock absorption capacity of the sample cartons with the standard and alternative MS-corrugation are considered as the investigation tasks. The samples were under the impact force. Shock absorbing properties of the multilayer cardboard packaging in size of 127 × 127 mm were evaluated under the following conditions: drop height, 610 mm; impact speed, 3.5 m/s; falling weight, 12.5 kg; pressure load, 340 kg. In this case, pressing force, impact energy, deformation value is recorded. As a result of the experiments, it was found that a three- and five-layer sample with MS-profile has better shock absorbing properties (as compared to a standard cellular cardboard of the same thickness). The application of seven- and nine-layer cardboard with MS-profile is inappropriate due to a minor advantage over a three- and five-layer sample.

Keywords:
cardboard packing, cellular structure, impact energy, MS-profile, depreciation, deformation.

Одно из важных условий сохранности упакованных продуктов — хорошие амортизирующие свойства тары. К упаковке предъявляются и такие требования, как технологичность изготовления, доступность, дешевизна и экологичность. Всем перечисленным требованиям удовлетворяет картон. Амортизирующие свойства такой тары зависят не только от толщины картонных листов, но и от их внутренней структуры [1]. Гофрированные картонные листы склеиваются в виде пчелиных сот, что позволяет компоновать плиты различной толщины [2, 3]. К перечисленным достоинствам такой упаковки следует добавить хорошую амортизацию нагрузки, которая действует вертикально картонному листу вдоль соты [4, 5].

 

Недостатком картонной упаковки с сотовой структурой является ухудшение амортизирующих свойств, если вектор нагрузки направлен не вдоль соты, не перпендикулярно листу. Из-за многочисленных, не поддающихся учету факторов воздействие нагрузки на упаковку строго вдоль соты — редкий случай, чаще всего нагрузка действует под углом к соте. В этом случае упаковка может разрушиться и не защитит от удара продукты [6]. Приходится ограничивать полезную массу контейнера, чтобы при транспортировке или кантовании не повредить защищаемый продукт [7].
