Packing Machine Expert Answers Dispersion Reasons for Packaging and Printing Industry

China's packaging and printing industry has a trillion market scale. In 2014, the total value of domestic packaging industry completed 1.84 trillion yuan. China's packaging and printing industry is scattered and the market concentration is very low. There are a total of 300,000 packaging companies in China, of which only 20,000 are above designated size, and about 90% are small and medium-sized enterprises. This shows that the combined strength of the clusters is small, the R&D capacity is not strong, and the transition is slow. Why does this happen? Please see the answer from the expert of the coating machine.

The experts of the box coating machine answer the scattered reasons of the packaging and printing industry. One: There are numerous small batches and personalized orders. The downstream of the packaging industry covers many fields such as food and beverages, medical daily chemicals, and home appliance communications. The types of packaging are mixed and the standardization is low, and it is difficult to achieve economies of scale. The standardization of PET bottles and metal cans is relatively strong, forming oligarchic enterprises; the demand for paper packaging and flexible plastic packaging is individualized, and the industry is very fragmented;

The experts of the box coating machine answer the reasons for the dispersion of the packaging and printing industry. Second: The value of the single product is low and the shipping radius is limited. The value of packaging products is usually low. Due to the limitation of shipping radius, packaging companies usually need to build close to customers to build factories, which leads to the decentralization of the packaging industry. Leading packaging companies need cross-regional distribution, and non-listed companies do not have the advantage in capital input capacity.

The experts of the box gluing machine answer the reasons for the dispersion of the packaging and printing industry. III: Low added value and low profitability. In addition to having certain technical requirements and packaging of high-end products, most small and medium-sized packaging companies have low product grades and added value, lack of design and research capabilities and independent innovation capabilities, poor profitability (margin ratio below 20%), and low return on investment. . Excellent packaging companies generally do not accept orders with low gross margins, and rarely lag behind small and medium-sized packaging companies.

Although China's packaging and printing industry is relatively decentralized, it does not mean that it will always be the case. The packaging and printing industry has great room for development. We have found the reason and we will make improvements to it. The packaging and printing industry will surely become more concentrated.

Female DVI Connector Series

Antenk DVI Series Digital Video Interface connectors are the standard digital interface for flat panels, video graphics cards, monitors and HDTV units. This series includes DVI-D (Digital), DVI-A (Analog) and DVI-I (Integrated Digital/Audio). Their unique crossing ground blades provide high speed performance at low cost. They are available in Straight or Right Angle PCB mount receptacles and mating male cable connectors. They support a data transfer rate of 4.95Gbps with a dielectric withstanding voltage of 500VAC. Each version features our specially designed contacts which improve signal performance and a zinc alloy shield that reduces electromagnetic interference (EMI).

Digital Visual Interface Cable Connectors

DVI ConnectorWith the advent of technologies such as DVD players, high-definition televisions, and even digital cable, the need for more advanced cables and connectors has increased. Digital Visual Interface (DVI) is one response to the growing need for interconnected systems, enabling digital systems to be connected to an array of displays. Yet DVI cables and connectors can also be complicated, and may lead to confusion between High Definition Multimedia Interface (HDMI) and DVI. Although the two systems have much in common, they service different niches of digital technology.

Digital Visual Interface

Older systems aren`t necessarily outdated systems. Although DVI preceded HDMI, it`s still widely used in both business and domestic settings. DVI connectors are designed to handle digital data transmission, incorporating three transmission channels in every connector link. The maximum bandwidth for data transfer is 165 megahertz, which is enough to relay up to 165 million pixels per second. Data is encoded for effective transfer, but a single link can handle around 4.95 gigabits per second of information. Double links can handle twice that amount.

Because a DVI cable carries information over a 165 megahertz bandwidth, complete digital resolution can be obtained. Using double link connectors increases the speed of transmission, but requires another cable. However, not many devices depend solely on a double link DVI, so this technolgy can be used on an as-desired basis.

Types of DVI Connectors

There are three general categories of DVI cable connectors: DVI-Digital (DVI-D), DVI-Integrated (DVI-I), and DVI-Analog (DVI-A). However, most connectors fall into one of the first two groups.

A standard DVI connector is 37 mm wide and has 24 pins, 12 of which are used for a single link connection. When analog is involved, four additional pins are needed to support the additional lines of an analog signal. It is not possible to cross from a digital source to an analog display or vice versa. In those instances, an integrated connector is probably the best option. There are five common types of DVI connectors.

DVI-I Single Link

This kind of connector has three rows, each with six pins. There are two contacts. Because the connector is integrated, it can be used with both analog and digital applications.

DVI-I Dual Link

A DVI-I dual link connector can also be used with both digital and analog applications, but is configured with more pins to accommodate a dual connection. There are three rows with eight pins each, as well as two contacts.

DVI-D Single Link

Specifically designed for digital applications, a DVI-D single link connector has three rows of six pins, and looks much like a DVI-I single link connector. However, a DVI-D connector has no contacts.

DVI-D Dual Link

Also made specifically for digital applications, a DVI-D dual link features more pins (three rows of eight) for dual connections. Like a DVI-D single link, a DVI-D dual link connector has no contacts.


This particular type of connector can only be used for analog applications, and has three rows of pins. One row has five pins, one has four pins, and the last row has three pins. Like single link connectors, a DVI-A link connector has two contacts.
