A cushioning packaging with peel as base material and preparation method thereof

Abstract

The present invention discloses a cushioning packaging with fruit peel as the base material, which is composed of a filling material and a carrier. The filling material is mainly pre-treated fruit peel particles, and the fruit peel particles are selected from fruit varieties with flocculent or spongy porous and fluffy shapes. The pretreatment process of the fruit peel is as follows: the outer skin of the fruit peel is removed, and the spongy and fluffy part inside is retained. The fruit peel is cut into small pieces and soaked in a preservative. The fruit peel soaked in the preservative is taken out and the excess soaking liquid on the outside is wiped off. Then, a waterproofing agent is applied to the outer layer of the fruit peel particles by spraying or soaking to form a barrier film to prevent the volatilization of water vapor inside the fruit peel, which leads to a decrease in cushioning performance. The pre-treated fruit peel particles are placed in each cavity unit of the carrier to prepare a cushioning packaging. The cushioning packaging is placed between the outer packaging and the packaged object as a filler. It solves the problems of the current chemical-made cushioning materials being difficult to degrade, the natural materials failing to buffer when exposed to moisture, and the high cost of bio-foaming manufacturing.

Description

Technical Field

[0001] The invention relates to the technical field of packaging materials, in particular to a cushioning packaging using fruit peel as a base material and a preparation method thereof. Background Art

[0002] With the development of industry, the performance, cost and environmental friendliness of industrial packaging are receiving increasing attention worldwide. Especially against the backdrop of the concept of green environmental protection, green, low-carbon and environmentally friendly packaging has become a hot topic of research in the industry. For fragile products such as electronic equipment, precision instruments, glass and porcelain, the selection and development of cushioning packaging is particularly important. Cushioning materials such as EPE, EPS and EPP are widely used in industrial cushioning packaging due to their excellent cushioning properties, ease of processing and low cost. However, their common disadvantages are that their raw materials are petroleum, which is a non-renewable energy source, and they are not easily degraded, causing white pollution. Many patents propose using natural materials such as straw and sucrose as raw materials to process them into cushioning packaging, but the disadvantages are complex processes, high costs, a sharp drop in mechanical properties when exposed to moisture, failure of cushioning performance, and limited usage scenarios.

[0003] Grapefruits are mostly harvested between October and November and are primarily grown in southern China. With the development of the logistics industry, grapefruit has become a popular fruit. Grapefruit peel accounts for 44%-55% of the fruit's mass. The thick, storable, spongy peel has a large inner layer of fluffy fibers and pectin, resulting in a large surface area and strong adsorption capacity. However, the peel is currently underutilized after consumption, resulting in a waste of resources, a large amount of waste, and environmental pollution. Currently, grapefruit peel, a porous, fluffy, or spongy peel, is widely used in furniture deodorization and formaldehyde removal applications due to its low cost, environmental friendliness, short growth cycle, and high yield. However, its use in industrial transport packaging is rare.

[0004] Although there are prior art methods that use grapefruit peels as cushioning packaging materials, they are mostly used as auxiliary ingredients and rarely as the main ingredient. In addition, the peels are usually crushed during the production process, which destroys the fluffy and porous structure of the grapefruit peels. One patent discloses a cushioning material in which the inner surface of grapefruit and corn starch are crushed and mixed, and then foamed with lactic acid bacteria to obtain a cushioning support skeleton, and the pores are filled with polylactic acid and paper fibers. However, the production process is complicated, especially the lactic acid bacteria foaming process is slow, and the production technology and environmental requirements are very strict. The production efficiency is low, and the time cost, labor cost and equipment cost of manufacturing are very high. It is difficult to put it into the manufacturing industry with high production volume as a process transportation packaging. In addition, after the patent fills the pores obtained by foaming with polylactic acid and paper fibers, although the overall compressive resistance is improved, the overall elasticity and cushioning performance are greatly reduced, which is not suitable for the packaging of products with low brittleness, such as fragile and easily damaged products. Another patent discloses a material made by crushing grapefruit peel and then mixing it with yeast powder for fermentation. In this solution, the grapefruit peel undergoes enzymatic hydrolysis, further deconstructing its inherent fluffy, porous structure. Given the current state of grapefruit peel utilization, a method that is both environmentally friendly and effectively utilizes its inherent structure is needed. Summary of the Invention

[0005] In response to the above shortcomings, the present invention provides a cushioning packaging with grapefruit peel as the base material, which solves the problems of current chemical-made cushioning materials being difficult to degrade, natural materials failing to buffer when exposed to moisture, and high bio-foaming manufacturing costs, and fully utilizes the role brought by the natural structure of grapefruit peel.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a cushioning packaging with fruit peel as the base material, the cushioning packaging is placed inside the outer packaging, and a layer of cushioning packaging is respectively provided on the bottom, four sides and top of the inner bottom of the outer packaging around the packaged object, the cushioning packaging comprises a plurality of cavity units connected end to end, the cavity units are sheet-like closed cavities sewn together by carrier non-woven fabrics or cotton cloth and other degradable and renewable materials with good toughness, the interior of the carrier is filled with filling material, the filling material is small pieces of fruit peel with spongy and flocculent internal soft tissue, and the small pieces of fruit peel are pre-treated by soaking in preservatives and waterproofing agents in turn.

[0007] Furthermore, the small pieces of peel are peels with flocculent or spongy porous and fluffy parts after removing the outer skin of grapefruit peel, citron peel, pomelo peel or tangerine peel.

[0008] Furthermore, the cushioning packaging is regularly arranged inside the outer packaging, the cushioning packaging is in a sac shape, the inside of the sac is the packaging material, the outer wall of the sac is a cavity unit composed of a carrier non-woven fabric or cotton cloth, the cavity unit is filled with filling material, the filling material is a small piece of fruit peel with a spongy, flocculent internal soft tissue, and the small piece of fruit peel is pre-treated by soaking in a preservative and a waterproofing agent in turn.

[0009] A method for preparing a cushioning packaging using fruit peel as a base material comprises the following steps:

[0010] (1) Select the fruit peel of the porous and fluffy variety with flocculent or spongy shape, remove the outer skin of the fruit peel, retain the spongy and fluffy inner soft tissue part, and cut the fruit peel into small pieces; determine the cutting size of the fruit peel according to the weight, size and crispness value of the packaged product; the heavier the packaged product, the larger the size or the smaller the crispness value, the larger the size of the fruit peel; the size range of the fruit peel small pieces is 10 to 30 cubic millimeters.

[0011] (2) Soak the cut pieces of peel in the preservative soaking solution for about 10 to 30 minutes. The soaking time can be appropriately increased or decreased according to the transportation and storage time of the packaged product. The longer the transportation and storage time, the longer the peel should be soaked in the preservative soaking solution. If the transportation and storage time of the packaged product is short or the transportation environment conditions are good, the soaking time can be appropriately reduced;

[0012] (3) Take out the peel piece soaked in the preservative, wipe off the excess preservative soaking liquid on the outside, soak the peel piece completely in the waterproofing agent and immediately take it out or spray the waterproofing agent on the outer surface of the peel piece to form a barrier film with moisture-proof and waterproof effects on the outer surface of the peel piece;

[0013] (4) Place the small pieces of peel that form the barrier film in a cool place and dry them in the shade for 2 hours to allow the solvent in the waterproofing agent soaking solution to evaporate and the peel particles to be fluffy and elastic;

[0014] (5) Use non-woven fabric or cotton cloth as a carrier to make a cavity unit, load the dried fruit peel pieces into the cavity unit formed inside the carrier, and then assemble one or more cavity units into a cushioning package. Control the size of the cavity unit and the loading quantity of fruit peel particles according to the brittleness value of the packaged product and the transportation and storage environment conditions. The smaller the brittleness value of the product or the worse the transportation and storage environment conditions, the higher the risk of product damage, and the larger the number or weight of fruit peel particles loaded. On the contrary, the higher the brittleness value of the product or the better the transportation and storage environment conditions, the lower the risk of product damage, and the smaller the number or weight of fruit peel particles loaded. The specific loading quantity and cavity unit size shall be based on the actual situation and the reliability test conclusions.

[0015] Furthermore, the preservative used in step (2) may be one of chitosan, mugwort powder, ammonium persulfate, and phosphate starch.

[0016] Furthermore, the preservative preparation method is to dissolve the preservative in water to prepare a preservative soaking solution, and the ratio of the preservative to water is 1 to 5:100 (g / ml).

[0017] Furthermore, the waterproofing agent in step (3) is composed of one of rosin, wax, polyacrylate, and water-based polyurethane.

[0018] Furthermore, the waterproofing agent preparation method is to dissolve the waterproofing agent in water or an organic solvent to prepare a waterproofing agent soaking solution, and the ratio of the waterproofing agent to the solvent is 1:3-5 (kg / kg).

[0019] A cushioning packaging with fruit peel as the base material is used in packaging electronic equipment, precision instruments, porcelain and other products with low brittleness, fragile parts or harsh transportation environment conditions.

[0020] The invention discloses an application method of cushioning packaging using fruit peel as a base material, which is used to fill the gap between packaging and outer packaging or to wrap smaller packaging.

[0021] The present invention has the beneficial effects of treating the peel tissue with a preservative, which extends the packaging's service life. Treating the peel tissue with a water-repellent prevents the evaporation of moisture from the peel, which would otherwise reduce its cushioning properties. The present invention is advantageous in that its primary raw material is grapefruit peel, a renewable material with low material cost, environmental friendliness, a short growth cycle, and high yield. Compared with commonly used cushioning packaging materials in the industry, such as foamed EPE, foamed EPP, and sponges, this material does not cause white pollution and is environmentally friendly. It also consumes some kitchen waste, enabling waste recycling. Furthermore, the cushioning packaging proposed by the present invention has a simple processing process, generates no industrial waste or pollution, and is easy to implement and mass-produce. Furthermore, the cushioning packaging proposed by the present invention has a certain degree of hygroscopicity, which can eliminate or reduce the use of desiccants. After absorbing moisture or water vapor from the air, its cushioning properties are enhanced. Furthermore, the entire processing process does not damage the original plant fibers and loose, porous structure of the peel tissue, maintaining optimal cushioning properties, making it very suitable for use as a cushioning packaging.
