Las bolsas plásticas se fabrican a partir de petróleo refinado que se convierte en etileno y luego en polietileno. El polietileno se corta en granos que se introducen en las fábricas de bolsas donde se extruye en películas de plástico y se les da color con pigmentos. Luego las películas se imprimen con diseños si es necesario y se cortan en la forma y tamaño deseado para cada bolsa usando parámetros programados. Se realizan controles de calidad durante todo el

Each colour of disperse dyes requires different raw materials. Because the range of colours is very large each colour has its own manufacturing process. The difference in the processes is primarily in the reaction period.

Plastic film is a thin continuous polymeric material. Thicker plastic material is often called a “sheet”. These thin plastic membranes are used to separate areas or volumes, to hold items, to act as barriers, or as printable surfaces.
Plastic films are used in a wide variety of applications. These include: packaging, plastic bags, labels, building construction, landscaping, electrical fabrication, photographic film, film stock for movies, video tape, etc.

This document gives a brief description on defoamer chemicals used in industry. Foaming is a problem in processing industry like, food, paper and pulp, paint and coating, printing, dyeing, oil drilling, boiler steam production, water treatment, waste management, etc.
We introduce ourselves as a Tyre Recycling Plant, Tyre Pyrolysis Plant Machines & Equipments manufacturing company with a professional approach that is aimed at result orientation. With our inception, we have etched a respectable place for ourselves in the recycling industry in India by installing quality pyrolysis machineries across India. Divya International today is one of the leading manufacturer of pyrolysis plant has a presence in pan India. Our excellent performance over the years has also earned us the status of a trustable name in the Tyre recycling industry.
Curled multilayer films may lead to problems during printing, lamination, thermoforming, etc. Curling occurs mainly in asymmetrical films.
Some tools are shown to reduce this curling effect.

1. Jeferson Javier duran Cristhian Mauricio Díaz meza Cristian rodríguez delgado Ema vera Fabricación de la bolsa plástica
2. Como se fabrican las bolsas Cualquier tipo de bolsa plástica o cualquier otro producto plástico que se produzca se obtiene a partir del petróleo. Es en refinerías especializadas donde se purifica el petróleo hasta llegar a convertirlo en un gas, el etileno. Este gas es posteriormente polimerizado y solidificado hasta crear lo que se llama polietileno El polietileno se corta en pequeños granos como los de arroz y normalmente se introducen en sacos de 25 kilos. Posteriormente es servido a las fábricas de bolsas
3. en la cadena de transformación de la granza de polietileno en una bolsa o film de plástico. con los parámetros exclusivos para ese pedido en particular. Una vez programada la extrusora, se comprueban las mezclas de material y aditivos necesarios para conformar el pedido: alta o baja densidad, con o sin polietileno lineal, deslizante o antideslizante, con o sin pigmento de color, superficie porosa o lisa, etc. La granza de polietileno es transparente, por lo que es necesario añadirle pigmento para conseguir el color deseado en el material. El pigmento se mezcla con la granza en las tolvas de las extrusoras. Se añadirá uno u otro pigmento dependiendo del color que se desee. Extrusión
4. El proceso se termina en esta etapa para algunos productos que se transforman. Tal es el caso del material retráctil o de las láminas Para los productos que lleven algún tipo de impresión, tales como una bolsa camiseta impresa o el símil papel impreso, el siguiente proceso es la impresión. Los productos que no vayan a ser impresos pasan directamente a corte
5. impresión el material proveniente de extrusión se introducen en un extremo de las rotativas flexo gráficas y se hace pasar la película de polietileno por unos rodillos y tinteros hasta que llegan al otro extremo con la tinta seca. Este proceso puede parecer muy sencillo en un principio pero es uno de los más complicados. Una ligera variación en las proporciones de las tintas, en la velocidad o en el tiempo de secado puede provocar que la impresión deseada sea totalmente distinta a la resultante El procedimiento termina aquí para productos tales como polietileno retráctil impreso o láminas en bobinas impresas.
6. lo primero que se hace es programar la cortadora con los parámetros necesarios para darle la forma que se desee, bien sea una bolsa camiseta, tipo mercadillo o una simple lámina. Se ajustan el ancho del producto, el alto, las medidas del fuelle, la altura y ancho Normalmente, se fabrican las bobinas de polietileno destinadas a bolsas de plástico con un ancho que es el doble o el triple del ancho real de la bolsa De esta forma, con el doble de ancho de la bobina sólo se necesitará la mitad de los metros de material para hacer el mismo número de bolsas
7. corte La única tarea que habrá que realizar es dividir el material de forma longitudinal en dos, tres o cuatro partes A continuación, y sólo para las bolsas tipo camiseta y algunas de asa troquelada, se les hace un fuelle o dobladura, que en el caso de las bolsas camiseta dará lugar a las asas, y en el de las asas troqueladas aumentará el tamaño de la base de la bolsa. Posteriormente, se procede a dividir el film de forma transversal mediante una cuchilla y unos cabezales que cortan y sueldan la base y la cabeza de las bolsas. La misma cortadora va formando paquetes
8. Durante todo el proceso de extrusión, impresión y corte se siguen unos controles de calidad para comprobar que el producto es conforme con los deseos del cliente y con los estándares de calidad. En caso negativo, el producto es retirado de la cadena de producción y reciclado en su totalidad para volver a reutilizar lo en la fabricación de bolsas de basura. Si no le sale como es:
