Stretch Wrap

详情

Here are the technical specifications and packaging details for each film type.

1. Stretch Film / Stretch Wrap

Used primarily for pallet unitizing and securing transport loads.



* Material: Linear Low-Density Polyethylene (LLDPE).

* Specifications:

* Thickness: 8 to *5 microns ($*0text{*-}**0$ gauge).

   * Pre-stretch Ratio: **0% to **0% (Machine grade).

   * Tensile Strength: ***0 MPa.

   * Cling: One-side or two-side cling options.

* Packaging Details:

* Hand Roll: Typically 4 rolls per carton; core diameter 2" or 3".

   * Machine Roll: Single rolls on a 3" heavy-duty paper core; palletized (approx. ***0 rolls per pallet).



2. General Plastic Film (PE/PP)

A broad category for bags, liners, and industrial covers.



* Material: LDPE, HDPE, or PP (Polypropylene).

* Specifications:

* Density: $0.**0text{*-}0.**5text{ g/cm}^3$.

   * Transparency: High clarity (PP) to translucent (HDPE).

   * Melting Point: $**5^circtext{C}$ (LDPE) to $**5^circtext{C}$ (PP).

* Packaging Details:

* Supplied on continuous rolls or perforated on a roll.

   * Wrapped in protective poly-sheeting to prevent dust contamination.



3. Agriculture Film

Specialized for crop protection, mulching, and greenhouse covers.



* Material: LDPE/LLDPE with UV stabilizers and Anti-Drip additives.

* Specifications:

* Thickness: ***0 microns (Mulch); *****0 microns (Greenhouse).

   * UV Resistance: Rated for 6, *2, *4, or *6 months of sun exposure.

   * Light Transmission: *0% to *0% for greenhouse grades.

* Packaging Details:

* Large format rolls, often folded (e.g., a 6m wide film folded to 1.5m for transport).

   * Heavy-duty outer protective wrap to prevent puncture during outdoor storage.



4. Shrink Film

Heat-sensitive film that contours to the shape of the product.



* Material: Polyolefin (POF) or PVC.

* Specifications:

* Thickness: *2, *5, *9, *5, or *0 microns.

   * Shrinkage Rate: *0% to *0% (Machine Direction); *0% to *0% (Cross Direction).

   * Shrink Temp: $**0^circtext{C}$ to $**0^circtext{C}$.

* Packaging Details:

* Center-fold (CF): Folded in half on the roll for easy insertion.

   * Single Wound (SW): Flat sheet for high-speed automated lines.

   * Cores are usually 3" and rolls are boxed individually.



5. Metallized Film

A decorative or high-barrier film coated with aluminum.



* Material: VMPET (Metallized PET) or VMCPP.

* Specifications:

* Metal Layer: **0 to **0 Angstroms.

   * Optical Density (OD): 1.8 to 3.0.

   * Oxygen Barrier (OTR): $<1.5text{ cc/m}^2/*4text{hr}$.

* Packaging Details:

* High-precision rolls wrapped in moisture-proof foil or vacuum-sealed bags.

   * Suspended packaging (end-caps) to prevent "flat-spotting" the film roll.



6. Transfer Film (DTF/Heat Transfer)

Carrier film for printing designs onto garments or hard surfaces.



* Material: PET (Polyethylene Terephthalate) with a matte or gloss release coating.

* Specifications:

* Thickness: *5 to **0 microns.

   * Coating: Single-side or Double-side matte.

   * Heat Resistance: Stable up to $**0^circtext{C}$ ($**0^circtext{F}$).

* Packaging Details:

* Rolls: Standard *0cm or *0cm widths; **0m length.

   * Sheets: A3 or A4 sizes in packs of *0 or **0 sheets.

   * Cartons include internal desiccants to keep the coating dry.
