double layer stretch film machine

 Double layer stretch film machine uses LLDPE as main material and adopts several kinds of resins to manufacture the single/double-side self-sticky stretch wrapping film. The film has good tensile strength,anti-pricking ability and impact strength. Its good shrinking memory function and self-sticky can make goods integrity to prevent goods from loosening and collapsing during transportation and being polluted by dust. The transparency and tensile strength of this product can make the packaging beautiful, economical and practical. The film can be widely used in wrapping of palletized goods. Its a good substitute for hot shrinking packaging film during transportation.   Technical Parameter:

Dynamic symmetry is a powerful compositional tool that artists, designers, and photographers use to create balanced, aesthetically pleasing images. Rooted in mathematics and geometry, it’s a system based on ratios and grids that help guide the placement of elements within a composition. Unlike static symmetry, which mirrors elements evenly, dynamic symmetry is about flow, movement, and proportional relationships that feel natural and organic to the human eye. This system has been used for centuries, particularly in classical art, but remains highly relevant in modern visual disciplines. Understanding how to use dynamic symmetry can drastically improve the structure and impact of your work.

To use dynamic symmetry, the first step is becoming familiar with the grid. The grid is not arbitrary; it’s derived from geometric ratios, particularly the root rectangles like Root 2, Root 3, and Root 5. These rectangles are created using diagonal and reciprocal lines that form internal divisions. The most common root rectangle used is Root 2, which maintains its proportion when folded in half. By using these ratios as the basis of your canvas or layout, you can construct a dynamic structure that naturally leads the viewer’s eye.

Once you’ve selected a root rectangle, overlay the dynamic symmetry grid on your canvas. This can be done digitally with software or manually using a ruler and compass. The key lines within this griddiagonals, reciprocals, and subdivisionsbecome guides for positioning key elements. You don’t have to align everything perfectly on these lines, but using them as anchors creates visual harmony and rhythm. Elements placed along these guides tend to relate to each other in size and placement, which creates a more cohesive and pleasing image.

The diagonals within the dynamic symmetry grid are especially important. These lines help build movement into your composition. For instance, placing a figure or object along a diagonal gives a sense of energy and direction. This is why many artists use dynamic symmetry to guide the flow of the compositionleading the eye through the work in a controlled but natural way. The grid helps avoid visual clutter by organizing space and guiding the relationship between positive and negative areas.

Dynamic symmetry is not rigid; it’s a flexible framework. You can rotate the grid, scale it, or adjust it to match your subject. For instance, in photography, you might adjust your camera angle or crop the frame to align major subjects with the grid lines. In painting or drawing, you can sketch the grid first, then build your subject around it. In graphic design, it helps balance typography, imagery, and whitespace by providing a hidden structure beneath the layout.

The power of dynamic symmetry lies in its ability to create compositions that feel right even if the viewer doesn’t consciously recognize the structure. It taps into natural human perceptions of proportion and order, using geometry that mirrors patterns found in nature. Mastery of this tool takes practice, especially in seeing how the grid can apply to complex subjects, but once internalized, it becomes second nature. Whether you’re designing a logo, composing a photograph, or painting a portrait, dynamic symmetry offers a time-tested path to visual excellence and creative control.
