Packing belt (PP, PET) is divided into PP packing belt (also known as polypropylene packing belt) and PET packing belt (also known as plastic steel packing belt), respectively the use of polypropylene and PET polyester as raw material production, respectively suitable for the weight of different objects packaging needs.
PP packing belt: PP scientific name polypropylene, polypropylene as raw material production of a light quality environmental protection packing belt, used for automatic baler, semi-automatic baler, manual baler, etc., suitable for bundling several kilograms to hundreds of kilograms of weight carton or pallet packaging lighter objects.
Features of PP packing belt:
1, polypropylene (PP) as the main raw material, material: polypropylene wire-drawing resin, because of its good plasticity, fracture pull
Strong strength, bending fatigue resistance, small density, tensile impact performance is good, easy to use and other advantages, has been in various fields
In a wide range of roles.
2, suitable for all kinds of packing machine (semi-automatic, automatic, manual packing machine)
3. Strong adhesive force, large tensile force, light weight, corrosion resistance, beautiful appearance, high-grade
4, bright color, yellow, white and black and other colors, you can choose
5, according to customer requirements and samples, the production of printing, printing ICONS and other special packing belt.
Classification:
(1) According to the surface color of the packing belt:
Colorless transparent PP packing tape.
Translucent PP packing tape.
Opaque PP packing tape.
PP packing belt in various colors.
(2) According to the proportion of polypropylene used in the production of packing belt:
New pure material PP packing belt, light material, bright color.
New and old mixed pure material PP packing belt, light material, slightly dark color.
Back material sandwich PP packing belt, heavy material, dark color.
(3) According to the packaging tools used:
Fully automatic PP packing belt, the width and thickness of the tolerance requirements are strict, small deviation.
Semi-automatic PP packing belt, the width, thickness tolerance and skewness requirements are low.
Manual packer with PP packing belt, the width, thickness tolerance and deviation requirements are general.
The plastic buckle is matched with thin PP packing belt.
PP flexible fiber belt for steel wire buckle.
(4) Divided into:
Use PP ordinary packing belt to bind cartons.
PP smooth tape for lapping tobacco.
Bundling RMB currency with transparent PP.
PP chemical fiber tape is used for binding chemical fiber package.
PP anti-static tape for electronic products.
Bundling heavy objects with PP heavy belt.
PP flame retardant packing belt for braided coal mine barrier.
As well as other special PP packaging belt for different industries.
5. Color:
White, red, yellow, green, blue, black, colorless and transparent, etc.
6, use
Used for packing cartons or other relatively light objects.
7. Production process:
PP packing belt production process: batching and mixing - plastic particles heating melting - extrusion into water to form a belt embryo - heating stretch molding - embossing - heating and cooling (finalizing treatment) - winding - packaging - storage.
8. Technical parameters of machine belt:
Width tolerance ±0.6mm
Thickness tolerance ±0.05mm
Fracture Tensile (pure material)
9 mm x 0.6 mm or greater 750 n
12 mm x 0.6 mm or greater 1000 n
13.5 mm x 0.6 mm or greater 1125 n
15 mm x 0.6 mm or 1250 n
Elongation at break ≤ 25%
Skewness ≤ 30mm/m
The appearance should be uniform color, neat and clear pattern, no obvious pollution, impurities, no cracking, no damage, perforation and other defects.
9, packaging
Packing with paper coupons, cartons, plastic film (bags) for outer packing, packing should be firm.
10, transportation,
The packing belt should be lightly loaded and unloaded in transportation to prevent sun exposure to the rain forest.
11, storage
The packing belt should be stored in a ventilated, cool and dry warehouse, and should be more than 2 meters away from the heat source. The storage period is one and a half years.
Ningbo Pacific Packaging Taps Co., Ltd. is a specialized packing belt unit, PP packing belt, packing belt manufacturers, understanding or need can call.
