Description

Technical Field

[0001] The utility model relates to the field of packaging materials, in particular to an environmentally friendly water leakage visible foil. Background Art

[0002] Support products are functional components commonly used in the process of packaging, storage and transportation. Their main function is to carry goods, provide support for the goods and facilitate transportation.

[0003] Current support products are usually made of flexible plastics such as polyester and polyolefin or pulp molded boards. They have excellent pressure resistance and pressure buffering capabilities, and can carry and support large items. However, in the actual production process, transportation is a relatively complicated process, and different products will have different functional requirements during transportation. For example, some fresh cold products need to be judged whether they have been thawed during storage and transportation, or some products may leak liquid during transportation.

[0004] The current solutions to these problems usually involve manual inspections and improvements to water leakage warnings on product packaging boxes, but both methods have major problems. The former cannot detect problems as soon as they occur, and although the latter can provide an immediate warning, adding functional improvements or labels to the packaging boxes requires additional costs, and the outer packaging is difficult to recycle and reuse. Utility Model Content

[0005] The utility model aims to provide an environmentally friendly visible foil for water leakage to solve the above problems.

[0006] According to one aspect of the utility model, an environmentally friendly visual background for water leakage is provided, which includes, from bottom to top: a supporting layer, which is composited by hardwood and softwood; a waterproof layer, which is arranged on the supporting layer and is transparent; a water leakage indicator layer, which is arranged on the waterproof layer and is white when dry and transparent when exposed to water; and a porous permeable layer, which is arranged on the water leakage indicator layer and has a plurality of micropores for liquid to penetrate.

[0007] In some embodiments, the support layer includes three layers of hardwood and two layers of softwood, wherein the hardwood is disposed at the top, the middle and the bottom of the support layer, and the softwood is disposed between adjacent hardwoods.

[0008] In some embodiments, the hardwood is in a plate-like structure; the softwood is in a honeycomb structure; and the hardwood and the softwood are bonded and fixed by starch paste.

[0009] In some embodiments, the waterproof layer is a bio-based waterproof coating, which is transparent after being coated as a film, and the bio-based waterproof coating is coated on the support layer.

[0010] In some embodiments, the water leakage indication layer is a wet transparent coating composed of starch, and the wet transparent coating is coated on the waterproof layer.

[0011] In some embodiments, the porous permeable layer is a hydrophobic starch gelatinized liquid containing a foaming agent, and the hydrophobic starch gelatinized liquid is coated on the water leakage indicating layer.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] The present application forms a structure similar to corrugated material by compounding soft and hard wood materials, so that it has good compressive strength and cushioning performance at the same time, and can fulfill the function of carrying goods. Moreover, they are all plant-based materials, green, environmentally friendly and degradable. When a water leak occurs in the carried product, water flows through the porous slow seepage layer and contacts the water leakage indicator layer. The water leakage indicator layer responds quickly and changes from white to transparent. The change is clear and easy to find, which plays an early warning function.
