The bursting of plastic and bursting boxes frequently occur.

[China Packaging Network News] The production of mid-range explosives and explosions is a topic that many printing companies have troubled with, resulting in product rework and scrapping, which in turn leads to a loss of customer resources and a significant loss to the company. How to better prevent and reduce the frequent appearance of such phenomena, which requires users to fundamentally identify the reasons for the right medicine, make timely and effective preventive measures.

Xiao Bian today specially invited technical experts from Hangzhou Zhonghe Packaging Materials Co., Ltd., which specializes in carton processing in the industry, to discuss issues related to explosives and explosive boxes. Their technical experts gave very detailed solutions! Do not talk nonsense, dry goods!

These phenomena occur frequently in our printing and packaging companies, but how do these phenomena occur? How should we respond?

I. Improper use of the product, resulting in poor adhesion of the product

Faced with improper operations, we can improve in three ways:

1. Glue Moisture Layer-Before using it, the customer must pay attention to fully stir the glue, because the glue raw material is more and the specific gravity is not the same, and it will produce sedimentation delamination for a long time;

2. Appropriate gluing amount control - less amount of glue, resulting in the product can not be effectively bonded, for the thicker paper and the box with a greater rebound, increase the amount of glue to not overflow the glue as the standard, manual operation should pay attention to wet adhesion Wet pressure, continuous pressure;

3. The pressure in the pressure box is not enough - Increase the pressure, and scientifically use a mechanical or pneumatic pump press. Pay attention to the 5-10 positive and negative positions with large rebounding boxes, uneven wine boxes, and special-shaped boxes and put them in a flat package to promote seamless contact between the boxes to prevent false sticking.

II. The glue model does not match, resulting in poor adhesion of the product

The choice of glue model and scientific use is very important:

1. No glue is a panacea. So customers must have targeted choices and use glue scientifically, such as:

Film sealing glue can not be used to bond the surface of the UV oil box; polishing glue can not be used for bonding plastic coated box, so do not think that a glue can stick to any type of paper box;

For chilled and frozen product packaging carton, and export hot countries, the customer should select the adhesive that meets the requirements of low temperature resistance, high temperature resistance and aging resistance, actively communicate with the production unit, and never blindly use;

The user must understand the glue performance indicators in advance to ensure that the product quality is stable and can be used to match the small-lot test glue with the product in advance. Scientifically choose to use the correct glue sprayer and viscose glue to avoid the explosion of boxes and explosives.

III. The lack of anti-explosive box experience and awareness of users

At the same time, users lack experience and precautions about product quality issues, which can easily lead to the occurrence of mass explosions. Prior to mass production, samples of small batches of products can be produced first, and product quality monitoring, risk prevention of explosions, and prevention of problems should be made. In particular, new materials and batches of raw materials should be used, and new process products should be tested in small batches.

Fourth, paper, film and other basic raw materials failed

There are many kinds of specifications in the paper and optical film market, which is one of the basic raw materials that are commonly used in the printing industry and are used in large quantities. The poor quality of raw materials directly affects the overall color box production quality, and it is also a raw material that is easy to be neglected and difficult to inspect. .

1. Demand to the film factory to declare technical indicators, purchase double-sided corona film, double-side corona pre-coating film, request corona value of 36-38 dyne, if the film does not meet the index, it can be added to the folder-gluer. With a plasma processor, corona treatment of the light film on the surface of the carton. Matte film products have a rough surface with a dyne value of 36-38, so matte film cartons have almost no popping phenomenon.

2. Transparent tape can be used to check whether the paper is powdered and whether the paper coating is powdered.

3. The transparent adhesive tape can be used to test whether the bond between printing gloss and paper is firm. If there is oil drop or color change, the adhesion is bad.

V. Fully understand and master the technical parameters of glue

Only when the user has a clear understanding of the technical parameters can the correct use of glue be made so that the glue can serve your carton better, so that you will not have any worries. This includes the high and low temperature performance, aging resistance, application range, storage conditions, adhesive properties, and environmental protection parameters of the adhesive.

6. Spray adhesive products need to be properly selected spray adhesive and spray product model

1. The glue sprayer should use professional spray glue, otherwise it is easy to cause the phenomenon of blocking the gun, reduce the production efficiency, and damage the performance of the equipment;

2. For different tray types, select different types of dispenser.

3. Use a damp cloth or sponge to wipe the tip of the nozzle after stopping or adjusting the machine halfway, so as to prevent the glue from being discontinuous and uneven, which will affect the adhesion of the paper box and form a bad paper box.

Then the question arises. In the face of such harsh production conditions, how can printing and packaging companies effectively avoid and crack it?

There is only one answer: Use the new type of glue 9988 spray glue and machine adhesive glue of Hangzhou Jupebao series to protect your hundreds of millions of paper boxes, so that you can worry!

Early sticky, fast paper break

In just 30 seconds, the speed of breaking paper is 20 to 50 times faster than similar products. It can be packaged immediately, saving delivery time.

High and low temperature performance

High temperature up to 100 degrees Celsius, 30-40 degrees Celsius higher than similar products;

The low temperature resistance can reach minus 30 degrees Celsius, suitable for frozen product packaging, and suitable for the climate conditions in the south and the north.

Full water, more environmentally friendly

No toxic and harmful substances, suitable for use in food, medicine, cosmetics packaging and other fields.

Wide range of applications

It can be applied to spray, roller, paper coated carton, polishing carton, gold and silver cardboard, and some UV products.
