5 polyolefin are filmy. The manufacturer that pack and user need to face the competitive pressure that grow day and day, the packing solution that can last is among them one of. Filmy product develops 5 structures from 3 structures, this one important promotion opened vaster choice space for product development. Be in current about but in the controversy eddy of durative development, specific power consumption and resource efficiency, low metric such catchword emerges in endlessly. Below such big environment, public expectation puts attention drop in ceaselessly excessive pack the resource that cause to waste the problem, rubbish that piles up everywhere, and ocean fills the safe menace that buries pair of food chain to cause these problems, this is opposite undoubtedly the industry that pack, especially flexible pack, produced tremendous effect. However, consumer often did not arrive conciously is, in fact, packing the sources of energy that production place wastes is used up under its packing production far, and pack can ensure packing won't leak, corruption and attaint, so, the itself that pack is not issue central issue, and should say more for the solution. Efficiency field is used in resource, flexible the photograph that pack compares the other solution that pack, because its are low weight advantage and force presses beautiful women or fragrant flowers. The manufacturer that pack and user need to face the competitive pressure that grow day and day, the packing solution that can last is among them one of. They send a hope to be able to pass the innovation in material, equipment or treatment craft respect to reform at raw material and mechanical equipment manufacturer, dissolve the pressure of own bear thereby. This Zhang Tu expresses OK and brief ground to reveal below piece, hope in case of German human relations Windmöller&The development process of the filmy product number of plies that the equipment institute that Hölscher (W&H) company sells makes, can see, the demand of equipment of monolayer film product is in in last few years glide quickly, and facilities of 3 filmy production produces an industry to have overwhelming advantage in the whole film that blow model (see a picture 1) . Nowadays a lot of applicable domains are to use 3 film, often can presswork it and block secondary floor, the reverse side BOPP or BOPET film regard lamination as material together. 3 active polyolefin on the market are filmy nowadays, its layer large percentage from 1 ∶ 1 ∶ 1 to 1 ∶ 6 ∶ 1. The surface layer photograph in composite material constituent compares other layer, have its special effect, it needs to realize specific function and character, for example burnish, sealed function and comfortable imprint quality. These functions often can carry raw material of use high quality only or additive comes true, and this backside means high cost again, because this manufacturer creates surface layer normally,get as far as possible thin. When filmy need is chromatic, those who contain dye is actually inside core layer, such since the smallest the contact that changed dye and mould metal face. Before craft can bring about painty precipitation to be in the wet surface of melt, this brought about longer cleanness and changeover time, and use afore-mentioned craft to be able to avoid completely. To satisfy extensive mechanical function requirement, 3 film often should use phyletic and various stock compound. Get together 5 filmy products also present Xi raw material a long-term development trend (see a picture 2) . Its develop basically is to be based on two direction. On one hand, use high quality raw material through specific aim and become depart of raw material mixture constituent monolayer, can achieve filmy performance optimize promotion, this not only can the ply of farther cut film, still can ensure filmy character at the same time quality is consistent (low metric) . On the other hand, raw material mixture constituent depart becomes the practice of monolayer, the structure can be used below certain circumstance simpler the raw material with accordingly lower cost, and the performance that won't affect film. Actually the focus of afore-mentioned two respects is to reduce raw material cost, and the largest share that this cost can make film produce cost normally. Crowd a manufacturing field in the film that blow model not only, this trend also applies successfully at other sphere stage by stage, for example, in the CPP film production that pushing model film field, through will mixing constituent depart is monolayer, this craft throws production already successfully to practice period of time, already developed what reveal improved data further thereby to produce a program to use a dominant position further now. The promotion of filmy and mechanical function packs circuit of content, downstream treatment, and be aimed at specific the solution that pack, can raise different special requirement to packing film. 5 filmy production can come true to mix raw material constituent depart to be monolayer already, such since can undertake to hardness demand in monolayer specific aim is adjusted. In 3 film, use tall tenacity normally (for example, PE-mLLD) with tall hardness (for example, HDPE) raw material mixture, and in 5 film, horniness material can from inside core layer moves to among them an intermediate layer. The space of layer and this mixture center layer is larger, promoted indifferent fiber permission filmy flexural strength thereby. The research project that ExxonMobil Chemical develops shows, the flexural strength promotion that this craft can pack high load capacity bag of film is amounted to 40% (see a picture 3) . In the meantime, through using raw material of high quality PE-mLLD, also can reform creep behavior. Nextpage hardness also is one of character with stereo bag the mainest bagging. Semi-manufactured goods of the bag that pack is special use polyolefin film and rear black-and-white BOPP or BOPET film to undertake lamination is produced (see a picture 4) , 5 compound film medium tall hardness material pledges from inside core moves intermediate layer, flexural strength also but be able to promote significantly. And because surface layer has comfortable imprint the requirement of gender and sealing, use high quality metal as much luxuriant with content raw material, and contain costly additive normally, also can make thinner with this craft (see a picture 5) . Use at baling the shrink packaging of carefe and other container is filmy, have polyolefin film to produce medium great portion at present. This kind packed this to also use 5 film, undertake distributinging through be functional character afresh in filmy monolayer, what can achieve specific aim to the product is improved. In 3 film inside core layer guarantees contractive function and puncture resistance, the project that W&H develops studies the result makes clear, through will tough metal luxuriant with content PE composition from inside core layer moves to 5 film medium other intermediate layer, 3 film that can compare a tradition promote puncture resistance significantly. In the meantime, pass in 5 film inside core layer is compound LDPE and HDPE material are qualitative, can limit the contractive rate that adjusts a product accurately according to applicable utility and manufacturing process, can amount to in promotion of small metric aspect 20% (see a picture 6) . The influence market to optical function rises increasingly to the requirement of filmy product, this is not only in mechanical performance side, also express respect of optical now function at the same time. Lamination surface needs to have not only high grade comfortable imprint gender and agglutinate sex, glossiness is very important also at the same time. A product can reach user hand through layer upon layer channel in, want to depend on the high quality packing solution that attracts eyeball greatly. Want to achieve this one goal, applicable high quality but also the can be used at surface layer material of high cost is qualitative at the same time, be like a metal luxuriant with content PE. 5 filmy structures can realize surface layer thinner, can reduce the use of raw material consequently, reduce cost thereby. In the meantime, because surface layer is thinner, the dosage of processing aid also can decrease accordingly. In addition, still can use can reclaim data will reduce raw material cost. In 3 film, will reclaim material is used at inside core layer, this material is flaxen normally character, after adding colorant, filmy whole presents even white. In 5 film, but choice general can reclaim layer of the core inside material qualitative park, place between layer of two colour developing, such exteriors can present ablaze white. Use this kind of technology, surface layer but the functional layer with paper-thin make it, thereby white dye and metal luxuriant with the contact between content mould surface layer can the smallest change, special mix to label film bale bag of product, such reforming quite can great shorten the cleanness of the mould and change time. If the graph is shown 7 times, can see apparently, the tradition cuts off 5 layers the layer is mixed among film inside of core layer cut off material is qualitative very thin, and the layer texture of 5 PO film differs significantly, its linear arranges means to be able to allow to use the model of moulds of a variety of the film that blow model and extruder. The place on epilogue put together is narrated, filmy product arrives from 3 structures the leap of 5 complex structures, the agile freedom that promoted a product development significantly is spent, meanwhile, also can resolve the central issue that manufacturer and cost of production of user place attention optimize. On one hand, in the filmy production of same ply, can use the raw material with lower cost, and beardless concern can affect filmy performance; On the other hand, use high quality raw material but cut and filmy ply, below the premise that ensures filmy function consistency, what also pledge for complex material whole produces cost is farther optimize open a space. Go to 5 from 3, those who increase is more than the number of plies that is a product, was to increase manufacturer to promote product function to promote oneself the infinite likelihood of competition ability more.
