Expansion Pack

What happens to your saved files when you uninstall a sims 2 expansion or stuff pack?

PC - Sims 2 and Expansions - Pc - Simulation

When you uninstall a sims 2 expansion or stuff pack do all your saved games, families etc permanently deleted. or are they

A. In Recycling Bin
B. Able to restore once reinstalling that expansion pack/stuff pack
C. Anything Else

when you un-install it will ask you if you also want to delete all your user files (saved games) If you select to leave the user files, they will stay where they are now. However, if you re-install Sims2 on that same computer, at that point all your saved games will be over-written, by new, blank user files.
To save all of your saved games so that you can keep them in case you re-install later, or want to move to another computer, you should make a manual back-up.
Just copy the folder
My Documents / EA Games / Sims2 or with Vista
User / Documents / EA Games / Sims2
to a second, safe location. I would suggest burning it to a DVD, or copying it onto a flash / USB drive.
I make a back-up of my user files every 2 weeks, or before I try and do anything that might mess with my game, like installing a major mod.

Higher Polymer Materials Packing Functions and Test

Abstract: This article elaborates on the operation characteristics and functions of flexible package materials.
Keywords: high polymer, flexible package, physical property, chemical property, and test

 

The application of polymer materials has eked out the shortage of past packages in terms of heaviness, complexity and single function, resulting in the wide application of polymer materials in industries of food, medicine and etc. Moreover, the customer-made nature of polymer materials makes it possible to design the packing structure according to characteristics of inner content and intentions of designers. Relating documents show that at present, domestic plastic packing (including vessel, tool) occupies approximately 30% of food packing in an escalation trend, with its growth faster than that of paper food packing.  Although domestic regulations on the quality of package material have been strengthened in recent years, food packing has hidden trouble in its safety and problems in packing quality. Therefore, from this year on,

Basic functions of modern package cover the three aspects of protection, convenience and promotion. Before arriving the hand of consumers, a packing-finished product must go through process of loading and unloading, transportation, storage, exhibition and etc, where many possible destruction factors to inner content exist in each of the links and where the protective function of the packing is demonstrated to prevent the damage created in terms of quantity and quality of products. The convenient function refers to filling, transportation, loading and unloading, piling, opening and etc, which have certain demands on properties of packing materials. For instance, to facilitate opening and consuming, mechanical property of materials is required. Promoting function of the packing is realized mainly through decorative design and shape design with reasonable and delightful color, pattern, and model. This relies on, to a great extent, the shape, the color, the texture, the transparency, the glossiness, the printing compatible and so on.

To food package, especially to flexible package, plastic films should possess some physical and chemical properties on the premise of the above-mentioned functions. The physical property generally mainly includes mechanical property, thermal behavior, optical property, barrier property, which can be called routine physical property if barrier property is excluded. The chemical property indexes refer to evaporation residue, potassium permanganate consumption, heavy metal content and organic solvent residue quantity and need to be tested with chemical agent or gas chromatography. This article will focus on routine physical property tests of materials.

2. Routine Physical Property Test of Packing Materials

Being the basis of quality guarantee, routine physical property test is to avoid the condition of package breakage before the predefined packing functions of products are fulfilled. Package breakage under this occasion will result in the failure of all protective functions of packing materials, even if special functional materials or materials with better chemical property are adopted. The routine test includes mechanical property test, thermal property test, and optical property test. Moreover, specific application occasions have specific demands on combustibility, electrical property, and dielectric resistance. Therefore, test items of materials should be decided according to the required application of package.

As for general flexible package manufacturers, the demand on mechanical property test of materials is the strictest.  It includes the stretch performance, the curving performance, the impact performance, the cutting performance, the friction performance, the heat-seal performance and etc. Any unqualified item may result in package breakage or failure of production operation. For instance, heatsealability of material includes two aspects: hot tack tested while the sealing part is still hotter (not cooled down to atmospheric temperature yet) and ultimate strength tested after the sealing part is cooled to a stable state. Heat-sealing package is widely used in the fields of daily chemical products, food and medicine. The filling process is normally finished by dropping products into package from a certain height, which has strong impact on the package bottom. If package bottom cannot resist the disruptive force of filling content, there will be cracked package. In order to effectively control the rate of failure package, hot tack (tested when the heat-sealing layer (sealant) is not completely cooled down) enjoys greater concern. The majority of packing products are piled up during transportation. If inner content is liquid or air-regulated packing form is adopted, package breakage will appear when the ultimate strength of package is unable to endure external pressure. That is why there is certain requirements to heatsealability of sealing part after being completely cooled down.

Thermal performance includes thermal stability, linear expansibility, low temperature test and etc. Among that, thermal stability and low temperature test attract the most attention of flexible packing industry. Thermal contraction of material is one of the indexes of thermal property, which later became one of the important test items of contractile film. Optical property is also one important index especially in packing light-sensitive food. Its test items mainly include luminousness and fog density.

3.Influencing Factors of the Test

Basically, routine physical test items can carried out with corresponding test instruments. To one item, test methods are not limited to one. Moreover, the test environment, the specimen dimension as well as the pretreatment will influence test results. Comprehensively speaking, the main influencing factors are test environment, pretreatment and test method adopted.

Test environment can impose direct influence on the result. For example, different temperature will result in significant changes of friction coefficient. The humidity can also influence some polymers, especially the high polarized polymers.

Both time and conditions of pretreatment will affect test results, which mainly results from the unconformity of specimen manufacture environment and incomplete elimination of internal stress. Test comparison should be performed under the same pretreatment environment and the pretreatment time.

There is no comparability between test results obtained with different methods. Property comparison of materials should be carried out on the premise of the same test condition (environmental humidity and test speed). To domestic flexible package industry, it is an effective way to improve data comparability by purchasing test instrument that is completely conforming to national standard.
