Abstract

The utility model discloses a completely degradable packing product which relates to tableware. The existing degradable tableware can harm human body because the surface contacting the food of the degradable tableware has residual pesticide. The utility model is composed of three or five layers of degradable materials, and the structure is A/B/A or A/B/C/B/A, wherein each A layer occupies 5% to 40% of the integral thickness of the tableware, and the B layer of the A/B/A structure or the B/C/B layer of the A/B/C/B/A structure occupies 30% to 70% of the integral thickness. The part contacting the food of the tableware of the utility model is made of nontoxic and harmless materials, and thus, the health of human body can not be influenced. The utility model is beneficial to environment protection and has the advantages of simple product structure and wide application, and the scaled, industrial, automatic and mechanization production can be realized.

Description

A kind of packing articles that can degrade fully

Technical field

The utility model relates to a kind of packing articles.

Background technology

The current packaging goods exist the problem that is not easy to degrade, for the packing articles that can degrade, owing to be that vegetable fibre injection moulding or compacting form, in use, Foods or drinks directly contacts with the food and drink tool, and contain remains of pesticide on the vegetable fibre, so can cause injury to human body more.

The utility model content

The purpose of this utility model is to provide a kind of packing articles that can degrade fully that human body is not had any injury, it is to be made by three layers or five layers of degradation material, its structure is A/B/A or A/B/C/B/A, wherein each A layer accounts for 5～40% of food and drink tool gross thickness, and the B layer of A/B/A structure or " B/C/B " of A/B/C/B/A structure layer account for 30～70% of gross thickness.Product is divided into three layers or five lamination systems to the utility model or injection moulding is made, with degradable but the material that contains remains of pesticide is placed on centre portion and food separates, inside and outside two-layer employing is heat-resisting, water-fast, oil resistant, nontoxic free of contamination material are made, and inside and outside double-ply thickness only is 5～40% of product gross thickness.The advantage that it had is: packing articles and food contact portion all are nontoxic material, so can not endanger the healthy of user; The all material of product all is a degradation material, the environmental protection that is beneficial to; Most of material of product is still degradable polymer and the synthetic preparation of made from plant fiber starch, so cost is low; The utility model product structure is simple, can realize scale, industrialization, automation, mechanization production, is beneficial to and applies.

Description of drawings

Fig. 1 is the cross-sectional configuration scheme drawing of the specific embodiment one, and Fig. 2 is the cross-sectional configuration scheme drawing of the specific embodiment two.

The specific embodiment

The specific embodiment one: present embodiment is the food and drink tool of being made by three layers of degradation material, the structure of food and drink tool transversal surface is A/B/A, wherein each A layer accounts for 5～40% of food and drink tool gross thickness, and the B layer accounts for 30～70% of gross thickness, and the gross thickness of described food and drink tool is 0.05～10mm.The utility model product is made sheet material by three-layer co-extruded casting films unit under 110 ℃, make the food and drink tool through molding, also can make membrane product with the blown film method then.Product is considerably beyond existing domestic and international similar products, and beautiful appearance is original in style especially, and overcomes the deficiency of existing procucts fully, has the market competitiveness.

The specific embodiment two: what present embodiment and the specific embodiment one were different is, it is the food and drink tool of being made by five layers of degradation material, its structure is A/B/C/B/A, wherein each A layer accounts for 5～40% of food and drink tool gross thickness, " B/C/B " layer of A/B/C/B/A structure accounts for 30～70% of gross thickness, and the gross thickness of described food and drink tool is 5mm.

Structure of the present utility model is not limited to the food and drink tool, and for other packing container, as long as adopt three layers or five laminates of starch, plant fiber degradable polymer manufacture, they are all within protection domain of the present utility model.

Claims
