(54) METHOD FOR PACKAGING BULK PRODUCTS IN FILM

one

The invention relates to the technique of packing bulk products in film materials, in particular, high-dust synthetic detergents, and can be used in the chemical and other industries.

The closest to the described invention to the technical essence and the achieved result is a method of packing bulk products in a film, which involves dosing, pressing products in the form of a briquette, destroying the briquette to a loose state and sealing it into a film 1 |

However, the known method does not provide high-quality packaging and sealing of bulk products into film materials, since the film material is dusty bulk and therefore it is impossible to heat seal or heat seal it. This is the main obstacle, due to which the problem of packing products like detergents, cleaning products like Chistol, Pemoxol

etc. in film materials can not be fully resolved.

The aim of the invention is to improve the quality of the weld and the maximum filling of the package.

This is achieved by the fact that in the proposed method of packaging is loose. products in the film the destruction of the briquette ds friable state is made after its sealing in the film.

The method is carried out as follows.

Bulk product to be packaged, investigated and pressed into a briquette. The briquette is then sealed into a lane with the help of hot air under pressure, after which the briquette is destroyed to a friable state, for example, in a vibrating hopper at a frequency of 200 Hz for 3 seconds or on an eccentric vibrating conveyor. The destruction of the briquette to a friable state after sealing it into a film eliminates the dusting of the film, allows heat sealing to obtain the most complete package. Example 1. Pemoxbl cleaner with components, / o: Hammer pumice 80 Technical sodium tripolyphosphate, 0 80 Sulfanol 80% 3.0 Soda ash calcined technical 12.0 with a bulk density of 0.683-0.833 g / cm, humidity, medium temperature 18-25 ° C, with a particle size of 200-500 μm and a volume of 500 cm pressed together at 10 kg / cm, obtaining a briquette 120 X 90 XX 50 mm. Briquettes are packed in a polyethylene tubular film, which is then sealed on both sides with hot air at 160 ° C and air pressure of 0.3-0.6 atm. The sealed briquette in the package is further destroyed on an eccentric vibrating conveyor 1C with a linear speed of 0.5 m / s and a length of 2 m. At the same time, the cleaner “PemokSol” has the following particle size, 7 ° in the package: particles less than 200 microns 95; from 200 to 500 microns - 5, which corresponds to grade I in accordance with the standard. Example 2. Cleaner Pemoxol, made according to the recipe of Example I, with a particle size distribution of & 00-500 microns and a volume of 500 cm is pressed with a force of 10 kg / cm 2, obtaining a briquette 120 X 90 X X 50 mm. Next, the briquette is packed in a polyethylene tubular film, which is sealed on both sides with hot air at 160 ° C and an air pressure of 0.3-0.6 aTm. The sealed briquette in the bag is then destroyed in a vibrating hopper with a frequency of 200 Hz for 3 seconds. At the same time, in the package the cleaning agent “Pemoxol has the following granulometric composition, / o: particles less than 200 microns - 92; from 200 to 500 microns - 8, which corresponds to the first grade in accordance with the standard. The proposed method, in comparison with the known technical solution of the same problem, provides the possibility of wrapping highly dusty products in a film with ensuring high quality of the weld, which is especially important in modern chemical industry for packaging chemical consumer goods. The method also provides for obtaining a maximum filling package, which improves the presentation of the package and reduces the consumption of film packaging material. The invention of the method of packing bulk products in a film, which involves dosing, pressing products in the form of a briquette, breaking down a briquette to a loose state, sealing it into a film, characterized in that, in order to improve the quality of the weld and maximum filling of the package, the destruction of the briquette to a loose state nor is it made after sealing it in a film.
