Abstract
The invention discloses a packaging film with high peel strength. The packaging film is composed of a PET(polyethylene terephthalate) thin film layer, a printing ink layer, a first polyurethane adhesive layer, a vacuum aluminizing PET thin film layer, a second polyurethane adhesive layer and a PE (polyethylene) thin film layer which are successively connected and closely fitted, wherein the PE thin film layer is composed of a linear low density polyethylene layer, a linear low density polyethylene and high pressure low density polyethylene mixing layer as well as a strengthening metallocene polyethylene, high pressure low density polyethylene and linear low density polyethylene mixing layer which are successively fitted; the first polyurethane adhesive layer and the second polyurethane adhesive layer are both composed of 10-15 parts by mass of polyester polyol, 4-6 parts by mass of polyisocyanate and 45-50 parts by mass of ethyl acetate. The packaging film disclosed by the invention has the advantages that the peel strength is high, and the security of content foods and drugs in a packaging bag is improved.
Description
Technical field
The present invention relates to the packaging film that peel strength is higher.
Background technology
The quality of packaging film will directly have influence on the safety of food and medicine, wherein the peel strength of packaging film is the comparatively crucial index that affects packaging film quality, and the peel strength that therefore how to improve packaging film on the basis of controlling manufacturing cost is a technical problem urgently to be resolved hurrily.
Summary of the invention
The object of the present invention is to provide the packaging film that a kind of peel strength is higher, its peel strength is higher, has promoted the security of content food and medicine in packaging bag.
For achieving the above object, technical scheme of the present invention is the higher packaging film of a kind of peel strength of design, is fitted tightly and is formed by the PET thin layer being connected successively, ink layer, the first polyurethane adhesive adhesion coating, vacuum aluminum-coated PET thin layer, the second polyurethane adhesive adhesion coating and PE thin layer;
Described PE thin layer is by the linear low density polyethylene layer fitting successively, LLDPE and hp-ldpe mixed layer, and strengthen metallocene PE, hp-ldpe and LLDPE mixed layer and form;
Described the first polyurethane adhesive adhesion coating and the second polyurethane adhesive adhesion coating form by 10-15 mass parts PEPA, 4-6 mass parts PIC and 45-50 mass parts ethyl acetate.
Advantage of the present invention and beneficial effect are: the packaging film that a kind of peel strength is higher is provided, and its peel strength is higher, have promoted the security of content food and medicine in packaging bag.
