Description
Technical field
The present invention relates to a kind of method of twining film with regenerated polythene production.
Background technology
The winding film of enterprise's production at present, the employing linear low density polyethylene resin is a primary raw material, the prestretched of product is generally 150-300%.Twine film if can produce, can guarantee product quality again, just can realize the recycling economy mode of " resource-product-regenerated resources-reconstituted product " with regenerated resources (regenerated polythene).Make it to have significant environmental benefit, social benefit and economic benefit.
Summary of the invention
The present invention is through production technology innovation and the improvement of raw material technical formula, can utilize the regenerated polythene production that contains slipping agent, opening agent to twine film, the tack of product is not damaged, reduce the production cost that twines film to greatest extent, and product have packaging functions such as antistatic, antiultraviolet, ensiling.
A kind of method of twining film of the present invention with regenerated polythene production, it is characterized in that: the coextrusion process of employing is:
Individual layer expressing technique: 25% regenerated polythene (not containing opening agent, slipping agent), the linear low density polyethylene (LLDPE) of 74.4-74.8% (metallocene linear low density polyethylene of available 5%-10% improves intensity), 0.2-0.6% tackifier;
Two layers of coextrusion process: 95% regenerated polythene and functional master batch, 5% linear low density polyethylene (LLDPE) and tackifier (0.2-0.6% is tackifier, the linear low density polyethylene (LLDPE) of 4.8-4.4%);
Three-layer co-extruded technology: (0.2-0.6% is tackifier, the linear low density polyethylene (LLDPE) of 4.8-4.4% for linear low density polyethylene (LLDPE) of (one deck) 5% and tackifier; (two layers) 10% linear low density polyethylene (LLDPE)s (virgin material) and functional master batch; (three layers) 85% regeneration linear low density polyethylene (LLDPE) or regeneration low density polyethylene (LDPE) and metallocene linear low density polyethylene and functional master batch.
In order to improve the ageing resistace of twining film and the intensity of film, except that the regenerated polythene of individual layer expressing technique does not contain opening agent, the slipping agent, the regenerated polythene of two layers of co-extrusion or three-layer co-extruded technology can contain the interpolation composition of opening agent, slipping agent; Functional master batch is antistatic additive, antiaging agent, ultraviolet screener or antistatic master batch, long-lived masterbatch, color masterbatch; The melt index of used resin raw material is 1.5-1.
The sticking evolutionary approach of twining film of other multilayer single face: (membrane structure: skin) 5% tackifier, LLDPE; (membrane structure: the middle level) 20% LLDPE, metallocene linear-low density polyethylene, functional master batch; (membrane structure: internal layer---this layer can be divided into two layers, three layers, with same manufacture of materials) 75% regenerated polythene, polyethylene, metallocene linear-low density polyethylene, functional master batch.
The invention has the beneficial effects as follows, be primary raw material with the regenerated polythene, twines film with LLDPE, metallocene linear-low density polyethylene improved production.Because the regenerated polythene resin property is relatively poor, adopt the LLDPE improved production, can improve the performance of film, the film prestretched reaches 2-3 doubly; Utilize the metallocene linear-low density polyethylene improved production, can allow the prestretched of twining film reach more than 300%, have higher mechanical strength and puncture resistance.Utilize multi-layer co-extruded production technology,, avoided the opening agent in the regenerated polythene material, the defective that slipping agent destroys the tack of twining film, the tack that has guaranteed to twine film through the raw material mix technique improvement.
