Standard voluntary standard for vinyl decorative coverings.
Purpose PVC film, referred to as PVC film, is usually used as a decorative laminate in combination with a variety of types of substrates.
The purpose of this standard is to outline the various properties of controllable PVC Films and to set performance standards or tolerance levels for these categories. 2.
Scope This standard covers the range of generally recognized types of PVC decorative laminate.
The specification will cover structure, thickness, size, surface treatment, measurement of physical properties and other properties.
All tests and standards proposed in this standard are related to the use of vinyl films on wooden substrates.
The base materials that are commonly used are scrap boards, medium-dense cardboard, cardboard, Laian plywood and hard plywood. 3. Requirements 3.
10 General products that meet this voluntary standard shall comply with all applicable requirements set forth in this section.
The test substrate will be 45-
47 lbs of industrial-quality crushing boards with density.
The adhesive will be epoxy. 3.
The types of vinyl PVC Films include four basic categories: 3. 15.

The design is printed on the back of the movie. 0018 in. (
Positive and negative 10%)
Vinyl resin that protects the print. 3. 15.
Semi-rigid film Semi-rigid or rigid PVC
This design is printed on the back of the film in reverse order.
Depending on the end use, the embossed and top coating are the options available.
From 4 miles to 24 miles. 3. 15.
Two sandwich films of semi-rigid or rigid PVCply laminate.
The opaque base film is printed on the top, and the top is laminated with a transparent cover.
Designed for mitrefold applications, the film offers relief and top coating as required for final use.
The measurements range from 5 miles to 24 miles. 3. 15.
4 solid color film Semi-rigid or rigid PVC, custom color matching in various shades.
The film is colored as a whole and can be printed, coated or embossed.
The measurements range from 3 to 12 miles. 3.
20 Construction 3. 20.
1 Formula for PVC the formula for PVCfilm is at the discretion of the manufacturer.
Since these particular preparations are proprietary in nature, the requirements for these preparations are not disclosed. 3.
25 color when made in pure color, PVC decorative film should be the same color in the roll provided to the customer.
While some slight color changes are allowed, the color should match the standard retained by the manufacturer or the sample provided to the customer. 3.
30 color matching PVC decorative film is generally made to match some specific colors or printed patterns.
These colors and patterns are usually high-pressure laminated materials, printed paper, painted plates or other printed vinyls.
Manufacturers usually name or number their patterns with their own names or numbers, which is not necessarily related to the above patterns.
Manufacturers can freely name and number their patterns according to copyright laws in the United States and Canada.
A reasonable competition should be considered a good business competition.
Customers must check all colors and printed patterns before using them to ensure that the match is appropriate.
All colors must be checked under a pre-agreed light source.
Samples must also be viewed under the same conditions; (i. e.
Vertical or horizontal positioning, etc. ).
Due to the change of light and color on all printing surfaces, there will be some changes in the production quantity. 3.
35 custom matching if the customer submits the specific color and opacity to be matched, the customer and the manufacturer will agree on the content to be matched; i. e.
, Laminated samples, paint chips, etc.
The manufacturer will provide the customer with color matching samples for approval in the form of manual samples.
Once approved by the customer, the material must be produced as a commercial match for the samples provided to the customer.
Both the customer and the manufacturer must be aware that PVC decorative materials can be used on other substrates other than the original matching materials.
Even if the color and opacity are the same, the two film samples may be different on different substrates or under different lighting conditions. 3.
The gloss of the 40 gloss PVC Decorative Film shall be consistent across the street and from roll to roll.
While some subtle changes are allowed, the gloss should match the standards retained by the manufacturer or the samples provided by the customer. 3.
45 The manufacturer of product thickness will specify the total thickness of the product.
Companies can produce films of any thickness they want, and different thicknesses may be required for various applications.
The following tolerances are generally accepted throughout the industry: 0-12 mil, [+ or -]10%; 12-20 mil, [+ or -]7. 5%;
20 mil and above ,[+ or -]5%. 3.
50 product width the width of a single main roller shall be specified in inches in increments not less than 1/4in.
The width tolerance should be negative 0, plus 1/4.
The width of a single slit roller shall be specified in an inch fraction and the increment shall not be less than 1/6 in. 3.
The 55 joint continuous coils of PVC decorative film can contain the joint.
To clearly mark the joint in the roller in order to remind the customer.
If there are joints, they will be tight and well laminated.
The joints are not separated when rolling from the core.
The length between the joints may vary depending on the roller and the inside of the roller.
The manufacturer will specify the number of joints allowed per volume. 3.
60 shrink vinyl film is thermoplastic and will shrink at high temperature.
Maximum shrinkage should be specified as less than or equal-
Length 10%, less than or equal to + 5% in the direction of the machine at 100 [test]degrees]
C 10 minutes. 4.
PVC film has many physical properties that provide benefits for end users.
The following categories represent common criteria for measuring these physical properties.
The typical attribute value is the average value of the test batch.
These numbers are not considered to be specifications where changes in the structure of formulas, meters and films affect these values.
The comparison between products should take these factors into account. 4.
