PE bag blown film should pay attention to?

PE bag packing bag is the most common in our daily life, used in all kinds of fruit and vegetable packaging, shopping bags, packaging of agricultural products and so on. As a user, I don't know how PE plastic bags production, think a bag is supposed to be a very simple work, very easy to make things. The following about the production of PE plastic bags production process: plastic particles - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Hot-melt mixing - - - - - - - - - - - Extrusion drawing - - - - - - Corona treatment - - - - - - Print - - - - - - Bag forming. Main is more than a few process, its simplified into three processes: blown film - - - - - - Print - - - - - - Bag making.

blown film process should pay attention to:

1, the ratio of raw materials: according to the requirements of the PE bag, make different proportions of raw materials. Such as antistatic, rust, oxidation, conductive, biodegradable and so on request, all kinds of auxiliary additives; Such as: red, black, yellow, and so on color requirement add various pigment; Such as: different according to the transparency, toughness, and tearing strength, vacuum, and so on a variety of different requirements, all kinds of brand or brand PE material; Such as: according to the requirements of special emphasis on higher transparency, tear force stronger and better open sex, change the ratio of the raw materials of all kinds of proportion.

2, in the process of blown film, need to be printed, must be corona treatment, the need to pay attention to the intensity of corona treatment, to ensure the intensity of corona treatment of PE bag of tube materials ( Dyne value) Enough to ensure that the printing ink adhesion.

3, blown film process, according to the special requirements of membrane material, single side, double side, ruffled, break, embossing, inflatable pressure point and so on a variety of different operations.

printing process should pay attention to:

1, printing ink, water-based ink, quick dry ink, invisible ink, color ink, ink, induction of anti-counterfeiting inks, conductive ink, ink low electronic ink, matte, and so on a variety of printing ink characteristics choose corresponding in ink.

2. Print: according to the detailed requirements of printing content, use the gravure ( Copper plate) Printing and flexo ( Offset) Printing, the two different printing way.

3, according to the printing content of fine and the complexity of color options: monochrome printing, monochromatic double-sided printing, single color printing, double-sided color printing and other printing way.

4, according to the special requirements of printing design:, anti-counterfeiting, conductive, adhesive properties such as resistance to select different ink or additives.

bag making process should be paid attention to:

1, the bag type: according to the PE bag, bag type flat pockets, special-shaped bag, solid bag, vest bag, since the glue bag, bag, even the volume bag, yuan line holding bag of different kinds, such as the use of bag making machine models are different, use method and auxiliary tools are there is a difference.

2, special requirements: the need to PE self destructive adhesive glue bags; In the gelatinize on PE bag; PE bag is needed in the yucca head; Need to bolt on PE bag; Need air holes on the PE bag and so on all kinds of requirements, use a variety of different auxiliary fixture.

3, packing: according to different packaging requirements of customers and use different packaging methods, such as: not to hurt, packed in carton packaging, according to a specific number, packing and so on different requirements to operate in a particular way.

so, when using PE bag, we don't look down upon a small bag, it is produced only filleting. Also let us know how to cherish it people work, pay attention to protecting the environment.
