Clamshell Blog

People on the food industry products, particularly in the health food become increasingly demanding, manufacturers Chuliao research and development in the food industry, not less fill people in need and in many Gongneng Shang, manufacturers of clamshell packaging by modern be realized, Mibu product Zi Shen’s defects, reduce costs and enhance the core competitiveness of the products. Here are some “advanced” packaging, is gradually changing products, changing our lives.

Paper-based composite packaging

This is a composite of a flexible, mainly foil type liner bag, embedded type, liquid type, etc.. Paper-based composite package to solve the main problem is the seepage problem, because the oil molecules small reason. Packed like cooking oil in Japan developed a composite box, very successful. Composite paper structure PE / paper / PE / AL / PET / PE, paper-layer composite substrate made by aluminum 6. As the composite layer with aluminum foil, its performance is better than glass bottles and plastic bottles, is safe and portable, and beautifully printed, increase the added value and competitiveness of goods.

New Compound “paper”

Super-strength composite paper has been developed abroad. The paper white as snow, thin as cicada’s wings, soft like satin, is still intact after repeated folding, also known as soft glass, and low prices. This kind of “paper” is basalt and Latin America in 2000 ℃ high temperature into the fiber, impregnated with phenolic resin and the infiltration of powder made of clay films. Mainly due to rock material, so long-term storage will not become brittle, moldy, moth-eaten, and can dyer & printer color, use wider. In addition, air-laid paper, sterilization paper, deodorant, paper, anti-charged paper, paper, anti-electromagnetic interference, high-absorbing paper (ie stealth packaging materials) and so on.

Deodorant packaging

Since the development of supermarkets and fast food, the rise in recent years abroad and a popular new concept of HMR, HMR market soon. Packaging materials in order to prevent the smell (that smell and odor) effects developed deodorizing packaging. Deodorant now has more than 40 kinds of packaging materials, mainly consists of three types:

A generic type of chemical odor that can remove nitrogen and sulfur compounds and the Department of compounds plus ammonia, dimethylamine, trimethylamine, hydrogen sulfide and other odor or smell.

Class B is a physical type, mainly used to remove hydrogen sulfide, carboxylic acid, and the like odor or smell, which is characterized by high concentrations of hydrogen sulfide odor effect is good.

C-like material is mixed odor type. Mainly made of activated carbon deodorant, deodorant ability of low concentrations of these materials good characteristics.

Deodorant packaging films for food packaging can also play a deodorizing effect of preservation. General deodorant packaging used that each have a special smell or odor of food, and agricultural products, aquatic products packaging.

Antimicrobial packaging

Microorganisms food corruption, so antimicrobial packaging has become a hot topic. To this end, Japan has added a new type of packaging materials inorganic antibacterial agent, successfully developed a series of antimicrobial packaging material, it has antibacterial effects various pathogens. The main features of the packaging materials are as follows: anti-bacterial effects of long duration; as antibacterial agents are gas-based, so the contents of the package without any adverse effects; stability.

In the packaging process, the thermal stability of high concentration and stability, no adverse effects on the working environment. Antimicrobial packaging materials mainly sheet, absorbent sheets, packaging film, anti-bacterial and other types of packaging. Sheet is to mixing to polyolefins and other antimicrobial agents.

Resin from repression, absorbing sheet is used as base material made of super absorbent polymers, often with film type and coating type. Such as non-woven / paper / mixed with antibacterial agents absorbent resin / paper / cloth.

Is now the widely used antimicrobial packaging film, add in the polyolefin film made of antibacterial agents on the most common microorganisms such as E. coli, Staphylococcus aureus, bean Phytophthora, wearing hold bacillus, Aspergillus niger, etc. have antibacterial effects.

High barrier packaging

As we all know, aluminum packaging materials superior performance, but opaque, for the successful development of a class of barrier experts new material. It is a good barrier, and other performance equal to or better than the plastic composite material. This is called GT composite packaging material, is deposited on the surface of a plastic film thickness 10 ~ 100um inorganic (eg nano-silica or titanium oxide) films made. Such nano-coatings, stable performance, even after high-temperature sterilization, its gas barrier, moisture, transparency is still as ever.

In recent years, the United States developed thermal efficiency liquid crystal polymer film (TLCP), from a special dense fibrous polymer composed of long chains, good strength and toughness. 2um thick liquid crystal polymer gas barrier properties of EVOH is very thick and 25um, but the price is much lower than the latter.

Cold seal packaging

Packaging machinery to be simple and convenient, energy saving, increased speed and efficiency to meet the needs of modern high-volume packaging, the use of low-temperature sealing packaging material is a necessary condition for low temperature sealed packaging. The so-called low-temperature packaging materials, that is, the film coated with a layer of natural rubber as the main component of cold seal coating and does not require heat-sealing the packaging material can be. It has a series of characteristics: First, the contents on the packaging does not produce heat-affected, and therefore particularly suitable for the packaging of tired of hot items; second is difficult to seal the substrate can be used; Third, simplify packaging machinery, reduce costs, save energy ; Fourth, to achieve high-speed packaging; 5 is a good cold seal, even under the seal strength at -20 ℃ will not decrease.
