Potential domestic manufacturers, foreign manufacturers and the scale of domestic and foreign production trend and forecast market conditions, supply and demand forecasting and business prospects part, domestic demand many aspects of manufacturers and contact information for PET plastic bottle products on the market situation and the direction of development discussed in detail, as PET plastic bottles deep processing technology trends important guide decision-making.

OPP bottles to overcome the shortcomings so far, since the OPP bottles PET bottle processing speed than the slow, physical properties are relatively poor, it has not been widely used. However, these shortcomings by being advanced equipment, optimized preform design, improved materials and PP resin developed specifically for PP bottles aid be overcome. ExxonMobil's research shows that the rational design of high-speed machinery use and allows OPP OPP preforms and PET can be in production, transparency, rigidity, toughness and sensory photogenic match. If you use such as Sidel company, SIGCorpoplast company or any other company manufactured high-speed, rotating heated SBM machine, OPP bottles will have extremely competitive.

PP of disadvantage 1, PP than PET is difficult to absorb and disperse heat, and OPP's sidewall thick preform (to achieve the same rigidity, OPP bottles need more than the same bottle PET bottle wall thickness). Thus, although PP preform injection stage in the process of low temperature (230 ℃), but you need to OPP bottle blow molding at 130 ℃ to complete, not only higher than the energy consumption of PET bottles, and molding and cooling cycles longer, resulting in OPP yield 25% lower than PET. 2, OPP stretch blow molding processing temperature is narrow, only 5 ℃, while PET is 15 ℃, thus increasing the probability of parking and waste outputs.

In addition, the OPP's stretching different ways. This is because some parts of preforms, such as the bottom and bottlenecks, may be less than the orientation of the bottle, more likely to cause atomization. Therefore, in order to close OPP transparent PET, preform and bottle design OPP must optimize orientation and draw ratio. 3, OPP rigidity lower, lower than the mean OPP bottle top load PET bottles and circumferential strength. In order to achieve the same rigidity, OPP bottles need PET bottle wall thickness than the same bottle. 4, OPP bottles of oxygen and carbon dioxide permeability of PET bottles is about 30 times, making it unlikely to be a barrier to contain carbonated drinks such need CO2 barrier containers unless coated or co-injection with the barrier resin.

Currently, many companies on the PP through the research and development, improve some deficiencies OPP bottles. For example 3988, to resolve problems include poor processing stability Haze (mainly bottlenecks and bottom), preform molding cycle length (PP addressed through enhanced nucleation) and stretch blow when. This Millad3988 AR agents have been widely used in vitamin, water, tea, juice, detergent and pharmaceutical packaging OPP bottle on the market outside the United States. ExxonMobil company, Basell company, Atofina Corporation and BPPetrochemicals company also launched AR PP grades, they use a catalyst having a low residual rate replaces the bottle can affect the appearance of a peroxide catalyst, OPP bottles with high transparency and high liquidity rigidity and toughness to achieve a good balance, thereby increasing OPP bottles in the packaging market competitiveness.
