Abstract

The utility model discloses a high-strength washing powder packaging film which has an integrated double-layer composite layer structure. An outer layer is a biaxially oriented nylon film (BOPA) layer, so that printing ink can be stably attached to the composite layer structure, and a printing layer is bright and exquisite in color; and an inner layer is formed by mixing high-density resin materials and metallocene linear low-density polyethylene, a high-strength PE layer is formed through three-layer coextrusion blow molding, and the packaging film has good sealing property, antistatic property, dust pollution resistance and heat seal performance. The packaging film has excellent mechanical properties and has the characteristics of high dust pollution resistance, good heat seal performance, drop resistance and penetration resistance, and the production cost is reduced while the performance is improved. The high-strength washing powder packaging film is suitable for serving as a packaging film for high-gram-weight high-strength washing powders.

Description

High strength washing-powder packing film

Technical field

The utility model belongs to the commodity packaging field, specifically a kind of high strength washing-powder packing film.

Background technology

At present, the packaging film of washing powder is divided into two kinds: medium-sized washing powder is selected BOPP/PE(bidirectional stretching polypropylene film/common polythene film usually) packaging film of structure; Super dense washing powder is selected PET/PE(PETG/common polythene film) packaging film of structure.Above-mentioned existing washing-powder packing film has following defective:

(1) peel strength is low low with pull-off force;

(2) anti-dust pollution poor performance;

(3) the puncture-resistant performance is poor;

(4) anti-drop performance is poor; Be not suitable for the packing of large grammes per square metre washing powder.

Therefore, in the washing-powder packing materials industry, urgent need will work out the stronger packaging film of a kind of mechanical performance.

The utility model content

The technical problems to be solved in the utility model is to provide a kind of high strength washing-powder packing film, is the lamination layer structure of the bilayer of integral type.Its ectomesoderm is the BOPA layer, can make printing-ink more stable be attached to above, make the color and luster of printed layers vivid, exquisite; Nexine mixes with metallocene linear-low density polyethylene for employing high-density resin material, and by the high strength PE layer that three-layer co-extruded blowing forms, has good sealing, antistatic behaviour and anti-dust pollution heat sealability.This packaging film not only has good mechanical performance, and has that anti-dust pollution, heat sealability are good, anti-to be fallen and the characteristics such as anti-puncture, has reduced production cost when performance improves.

For solving the problems of the technologies described above, technical solution adopted in the utility model is:

A kind of high strength washing-powder packing film is the integral type lamination layer structure, and described composite bed comprises outer field BOPA(BON biaxially oriented nylon film) layer and the high strength PE layer of nexine.

As a kind of restriction of the present utility model, described high strength PE layer is three layers of composite bed that coextrusion blow forms, and these three layers of composite beds are from being followed successively by near the BOPA layer: HDPE mixing LDPE mixing LLDPE layer, HDPE(high density polyethylene (HDPE)) mix LDPE mixings antistatic additive layer, LDPE(low density polyethylene (LDPE)) mix the MLLDPE(metallocene linear-low density polyethylene) mix the LLDPE(LLDPE) layer.

As another kind of restriction the of the present utility model, the thickness of described BOPA layer and high strength PE layer is respectively: 15 μ m and 70-125 μ m.

Limit as of the present utility model the third, be bonded in one through aqueous binder between the BOPA layer of described high strength washing-powder packing film and PE layer are two-layer.

The utility model also has a kind of restriction, is attached with the water color ink printed layers on the corona surface of BOPA layer.

Owing to having adopted above-mentioned technical scheme, the utility model compared with prior art, obtained technological progress is:

1. high strength washing-powder packing film provided by the present invention, nexine in its composite bed is the PE layer, adopt the high-density resin material to mix with metallocene linear-low density polyethylene, and form by three-layer co-extruded blowing, have high strength, good sealing, antistatic behaviour and anti-dust pollution heat sealability.It is good plastic body that internal layer in its three layers of composite bed has adopted metallocene linear-low density polyethylene, its film of making have tearing strength high, anti-ly fall, the characteristics such as anti-dust pollution, sealing are good; The intermediate layer has added the antistatic resin material, has increased its anlistatig performance; Add high density and low-density resin material in skin, made it that good antipollution sealing be arranged, increased the bulk strength of packaging bag.

2. high strength washing-powder packing film provided by the present invention, the skin in its composite bed is the BOPA layer, can make above printing-ink more stably is attached to, and makes the printing color and luster vivid, exquisite.

3. the detection index of the high strength washing-powder packing film that relates to of the utility model is: peel strength 〉=3.5N/15mm;

Pull-off force 〉=60N/15mm; 1.2 falling, rice do not break; Heat seal strength 〉=50N/15mm.

This packaging film not only has good mechanical performance, and has that anti-dust pollution, heat sealability are good, anti-to be fallen and the characteristics of anti-puncture, has reduced production cost when performance improves.

The utility model is applicable to the packing of large grammes per square metre, high strength washing powder.

The utility model is described in further detail below in conjunction with Figure of description and specific embodiment.
