Abstract

The invention provides a multilayer pulp blister. The multilayer pulp blister comprises a high-density bottom layer, a film layer, buffer layers and a protection and decoration layer which are arranged sequentially, wherein the high-density bottom layer is used for protecting the pulp blister against direct contact with a product; the film layer serves as a water-resisting, heat-resisting or electrostatic protective layer, the buffer layer is used for buffer protection of the product from external force; the protection and decoration layer is used for outer protection and printing appearance decoration. The layers of the multilayer pulp blister have different densities, so that the pulp blister with variable density is realized, the layers with higher densities can provide strength support, and the layers with lower densities can provide impact buffer, so that the multilayer pulp blister has good functions of shock absorbing and buffering and advantages of environmental protection and energy saving.

Description

technical field [0001] The invention relates to the technical field of pulp bulbs, in particular to a multilayer pulp bulb. Background technique [0002] Pulp blister is a commonly used cushioning material at present. The existing pulp blister technology uses a single layer of pulp to form, that is, it needs to be made separately in layers. Each layer uses one or more sets of molds, and then they are bonded, which is easy to produce The side seams are damaged, and more manpower is required during the construction process, and more materials and costs are consumed discontinuously. Because it adopts a single layer, it cannot be used in one piece or multiple times, and it is also impossible to make multiple layers of pulp blisters in local positions, so the density cannot be changed, and only shells with uniform density can be made. The shock-absorbing and shock-proof effect is single and cannot be effectively and quickly changes or absorb vibration waves. Contents of the in...
