Following China's addition of 7 million tons of new papermaking capacity and 46 million tons of planned capacity in 2020, 2021 marked another banner year for China's paper industry: on the one hand, paper prices continued to soar, and paper mills raked in huge profits; on the other hand, booming exports and the national wave of plastic bans and restrictions greatly boosted market confidence. Meanwhile, the paper industry has launched new projects one after another, with investments routinely reaching tens of billions of yuan — a rarity in the world. After many years in which market demand stalled at 100 million tons, new papermaking capacity is surging

Author: Guangzhou Tongze Machinery Co., Ltd. A006 - Control Difficulties and Countermeasures in Aluminum Foil Lamination Aluminum foil lamination is a difficult structure in the solventless lamination process, and many users find this structure rather hard to master. The root causes of the problems lie mainly in the following aspects: relatively high rigidity of aluminum foil, very small thickness of aluminum foil commonly used in flexible packaging, and relatively low initial tack of the adhesive. The most common structures for aluminum foil lamination are PET/aluminum foil/PE, or BOPP/aluminum foil

Water-based inks are Newtonian fluids, so their stability is relatively poor, which is mainly manifested in the following three aspects. ①Pigment sedimentation. Before use, the ink in the ink drum must be stirred evenly, and during printing the ink in the ink trough must also be stirred frequently to prevent pigment sedimentation from causing a certain difference between the printed color and the standard. An effective way is to use a fully enclosed doctor blade, so that the ink remains in a stirring and flowing state under the operation of the ink pump.

Construction of Hong Kong's first plastic recycling facility capable of reaching near food-grade quality held its groundbreaking ceremony on September 25.

1. The factory has stopped production, but that doesn't mean it has gone bankrupt! The main thing is spending your own money to keep skilled masters on. If you let all the masters go when business is bad, where will you find people when orders come? Who will do the work? Newly hired people can't get the hang of it right away. 2. During this period, I've been taking orders that earn no money at all, just to keep the workers fed. There were once two years when I earned less than a single worker, simply to wait for the market to turn. Two

Incomplete curing of adhesive is one of the most common quality problems in the lamination process. There are many causes of this problem. For example, inaccurate mixing ratio, excessive moisture or alcohol content in the solvent, too high ambient humidity, improper storage of leftover adhesive, and insufficient crosslinking degree of the adhesive itself can all lead to incomplete curing. Among them, particular attention should be paid to the effect of polyurethane ink on the incomplete curing of adhesive. The following is a specific case: The structure of this sample

[Key Points] High-temperature retort pouches are a high-end product in flexible packaging. On one hand, profits are high: the profit per pouch is several times that of ordinary pouches of the same specification. On the other hand, risks are high: there are many problems caused by discoloration, reduced peel strength, pouch bursting and so on. In mild cases, downstream manufacturers return the goods and orders are lost; in severe cases, compensation must be paid for a large sum covering the contents of downstream products during storage. An analysis is now made of the frequently occurring bursting problem. 1. First, analyze the boiling pouch: water is filled into the pouch as specified

PE plastic packaging film is made from film-grade polyethylene pellets, processed into a fixed film form with a thickness of 0.002-0.3 mm by blown film or cast film extrusion.
