Problems solved by technology

However, in the printing process of biodegradable polyester films, there are often cases of poor printing (the ink is not completely adhered to the film, or the adhesion strength is not enough) or excessive printing (too much ink adheres, and the logo is unclear). poor printing performance

[0038] According to the formula shown in Table 1, mix PBAT, PLA, ADR4370, organic fillers, inorganic fillers, plasticizers, surfactants, waxes and other additives and tetrahydrofuran and put them into a single screw extruder at 140℃-240 Extrude and pelletize at ℃ to obtain the composition. The performance test data is shown in Table 1.

[0039] Performance evaluation method:

[0040] (1) Evaluation method of printing performance of biodegradable polyester composition film:

[0041] Taking biodegradable polyester composite films with different printing effects, according to the clarity of the printed label and the ink adhesion on the film surface, the different printing effects are graded as follows:

[0042] Level 1: The label is clear, and there is no excessive ink adhesion to the film;

[0043] Level 2: The label is clear, and a small amount of excess ink adheres to the film;

[0044] Level 3: The label is basically clear, with more ink sticking to the film;

[0045] Level 4: The labe...

Abstract

The invention discloses a biodegradable polyester composition. On the basis of the total weight of the biodegradable polyester composition, the weight content of tetrahydrofuran is 3-200 ppm. By adding tetrahydrofuran in the composition, the content of tetrahydrofuran in the composition is controlled to be within the range of 3-200 ppm, the bad printing phenomenon of the biodegradable polyester composition in the printing process can be greatly improved, the phenomenon that printing ink disengages from a film material is avoided, the phenomenon that because printing ink is too much, the printing ink adheres to the film material is also avoided, and therefore a thin film has good printing performance.

Description

Technical field [0001] The invention belongs to the field of polymer material modification, and specifically relates to a biodegradable polyester composition with excellent printing performance. Background technique [0002] Biodegradable polyester is a type of polymer material that uses biological resources as raw materials. Compared with petroleum-based polymers that use petrochemical resources as raw materials, biodegradable polyester can be degraded in the process of biological or biochemical action or in the biological environment. It is currently very active in the research of biodegradable plastics and the best degradation in the market. One of the materials. [0003] Biodegradable polyester film is currently one of the important application areas of biodegradable polyester, including food bags, garbage bags, shopping bags and mulch. In the process of blowing biodegradable polyester to prepare films, ink is usually required to print required labels and logos on the film. ...
